The thing about Red Dragon Archfiend and Resonator as two archetypes supporting each other is that Resonator has so many cards that just allow you to turbo out practically any of your Red Dragon Archfiend Synchro Monsters that you may be playing in your Extra Deck. But because they are able to do this so easily, they have restrictions like locking you into Synchros or locking you into DARK Dragon Synchros. Because of that, it is not that easy to make a Red Dragon Archfiend Prediction Princess Deck. Red Dragon Archfiend has 1 Level 9 monster in Hot Red Dragon Archfiend Abyss which is a Level 9 DARK Dragon Synchro Monster that requires a Tuner monster and a non-Tuner DARK Dragon Synchro Monster as material. As a Quick Effect, you can target a face-up card your opponent controls and negate its effects until the end of the turn. And if it inflicts battle damage to your opponent, you can target a Tuner in your GY and Special Summon it in Defense Position. Hot Red Dragon Archfiend Abyss is a really good form of interruption and negation as it is a proactive effect rather than a reactive effect which allows you to negate cards on field even if your opponent attempts to Chain Block their activations. Because of this, I really wanted to find a way to get to Abyss, target it with World Legacy Monstrosity to get Prediction Princess Bibliomuse and another Level 9 out from the Deck, use Abyss and a Level 9 to do the Aggregator line, and then Special Summon back Abyss from GY to use as interruption/protection on the opponent's turn with its effect. There are a couple of ways that we can achieve this: World Legacy Succession, Nine-Lives Cat, or Cloudcastle. But I just find trying to make Nine-Lives Cat or Cloudcastle in addition to the other things we must do as too much to ask for. We already have a enormous combo line that we have to go through to get to Abyss itself, and we can't really maneuver our way to Cat or Cloudcastle that easily. Succession works best after those two other options, but at the same time, I decided that would be only the case if we manage to draw Succession. Doing it everytime is also a bit much to ask (or that's at least what I figure), so we will bring back Abyss with Succession if we do have the Succession only. Next issue I had to address was the Synchro Material requirements. Hot Red Dragon Archfiend Abyss's Synchro Material requirements are not as generic as compared to Crystron Quariongandrax or Crystron Phoenix, so I had to find a way that made it easy on myself and was able to be incorporated into our main combo lines of our Red Resonator Predaplant engine. At first, I tried using Diabellstar the Black Witch and Original Sinful Spoils - Snake-Eye to get both Diabellstar and a copy of Jet Synchron onto the field. That's because Diabellstar is a 7 and Jet is a Level 1 who can Synchro into a DARK Dragon Synchro like Scarred Red Dragon Archfiend, and then Jet can bring itself back to Synchro with that DARK Dragon Synchro to make Abyss. That did work, but it required you to draw Diabellstar access in addition to your Red Resonator Predaplant engine because Diabellstar and Jet would get you Abyss while Red Resonator and the Predaplants would get you to Monstrosity through Ib. So I scrapped that and ended with this. It is similar in concept to our combo for Power Tool Braver Dragon Prediction Princess in using Ultra Polymerization to make Predaplant Ambulomelides who can search for Predapruning and while also being able to make Ultimaya Tzolkin with Ib the World Chalice Justiciar. Except, Ib would then float into World Chalice Guardragon while you can set Predapruning to trigger Tzolkin for Scarred Dragon Archfiend. Flip Predapruning for Melides from GY and Tribute it for Tuner 6 access in Predaplant Banksiogre to go into Shooting Riser Dragon with WC Guardragon, and use it to send a 6 from Deck to make it a Tuner 1 to Synchro with Scarred to make Abyss with Monstrosity Access. 2.5-card combo as per usual: Red Resonator, Predaplant Ophrys Scorpio, and a monster to send to GY. Normal Red Resonator and Special Scorpio. Scorpio sends a monster from hand to GY to Special Summon Predaplant Darlingtonia Cobra from Deck. Cobra searches Ultra Poly. Pay 2000 with Ultra Poly to Fuse Cobra and Scorpio into Ambulomelides. Ambulo adds Predapruning from Deck to hand on Fusion Summon. Banish Ultra Poly from GY targeting Ambulo to bring back Cobra and Scorpio from GY. Synchro Red Resonator and Cobra into Ib the World Chalice Justiciar. Ib adds World Legacy Monstrosity from Deck to hand. Send Ib and Ambulo to GY to Special Summon Tzolkin from Deck. Ib triggers in GY to Special Summon World Chalice Guardragon from Deck. Set Predapruning. Tzolkin triggers to Special Summon Scarred Dragon Archfiend from Extra Deck. Flip Predapruning to Special Summon back and equip Ambulomelides from GY. Ambulo targets and Tributes itself to Special Summon Predaplant Banksiogre from Deck. Synchro Banksiogre and Guardragon into Shooting Riser Dragon. Shooting Riser sends a Bystial from Deck to Gy to make itself a Level 1. Synchro your Level 1 Shooting Riser and your Level 8 Scarred Dragon Archfiend to go into Hot Red Dragon Archfiend Abyss. Scarred Dragon Archfiend triggers to Special Summon Red Dragon Archfiend from Extra Deck into the EMZ. Activate Monstrosity targeting Abyss for Bibliomuse and Deus-X from Deck. Link Tzolkin and RDA into I:P Masquerena. Xyz Abyss and Deus-X into Mereologic Aggregator and use its effect to send Herald of the Arc Light from Extra Deck to GY which triggers Herald to search for Prediction Princess Tarotrei. Detach Deus-X from Aggregator and reattach Herald from GY to Aggregator. Link Aggregator and Scorpio into Sky Striker Ace - Camellia. Herald Triggers again to search for Underworld Ritual of Prediction. And it is the usual Prediction Princess combo from here. Is this a good Deck? Not really. You have a couple of bricks in the Deck that you really do not want to draw, and while it is a 2.5-card combo to achieve all of this, you don't really end on anything that has to do with RDA. Do you need to play Tzolkin? I would recommend it because it is difficult to find a way to make both Ib and a DARK Dragon Synchro for Abyss without it. Do you need to actually play Scarred Dragon Archfiend and Red Dragon Archfiend? No. If anything, it just thematically goes better with Abyss and helps to give you more Link Material. You can definitely just play Hundred Eyes Dragon and be done with it, and you could possibly even do something cool with Hundred Eyes if possible (haven't tested it though). Can you actually end on Abyss? Yes, you could through utilizing Succession like I described earlier, or if you already drew Bibliomuse, you can use the Bibliomuse and the Deus-X you got off of Monstrosity to go into Aggregator instead of using Abyss so that you can keep it as a part of your endboard. Reminder that this is just me experimenting with Level 9’s, so don’t actually play this. It is really bad.
For the Main Deck monsters: 3 Prediction Princess Tarotrei, 1 Prediction Princess Tarotreith, and 3 Prediction Princess Bibliomuse. Tarotrei can Quick Effect flip a monster on field face-up or face-down and during your End Phase, she can Special Summon a Flip Monster from hand or GY face-down. Tarotreith must either be Ritual Summoned or Special Summoned via Tarotrei’s End Phase effect. Her Flip Effect Special Summons a Flip Monster from your Deck face-down and she can also Quick Effect flip any number of your monsters face-up or face-down. Bibliomuse can Special Summon herself back from the GY face-down if she is Tributed and sent there. Her Flip Effect adds a Prediction Princess monster other than herself and a Ritual Spell from your Deck to your hand and while she is face-up on the field, your Ritual Monsters gain targeting and destruction protection from your opponent’s effects. 2 Deus-X Krawler which negates all activated monster effects on your opponent’s side of the field after it has been flipped face-up and if it is destroyed on field, you can search for a Level 9 monster with a different Type and Attribute than it. 1 Predaplant Banksiogre which is just a Level 6 Tuner we can get from Deck. But it does have a mandatory effect that activates when it leaves the field to place Predator Counters on your opponent's monsters, so it is important to remember that. 3 Predaplant Ophrys Scorpio which sends a monster from hand to GY on Normal or Special Summon to Special Summon a Predaplant monster from Deck except itself. 1 Predaplant Darlingtonia Cobra which adds a Fusion or Polymerization Spell Card from Deck to hand if Special Summoned by the effect of a Predaplant monster once per Duel. 2 Lonefire Blossom which tributes a Plant to Special Summon a Plant from Deck. 3 Red Resonator which Special Summons a Level 4 or lower monster from hand on Normal Summon and on Special Summon, it can target a face-up monster on field to have you gain LP equal to that monster's ATK. 1 World Legacy Guardragon which is a Level 1 monster that we can Special Summon off of Ib the World Chalice Justiciar. 1 Bystial Magnamhut and 1 Bystial Druiswurm which are Level 6 monsters we can send from Deck for Shooting Riser and they double as interruptions as well. Finally, 3 Ash Blossom & Joyous Spring.
Spell/Traps: 1 Instant Fusion for Master of Ham. 1 Ultra Polymerization which Fusion Summons using 2 monsters you control by paying 2000 LP and this activation cannot be responded to by either player. You can also banish it from Gy and target a Fusion Monster that was Summoned by its effect to Special Summon all of the Fusion Material Monsters from your GY with their effects negated and ATK/DEF reduced to 0. 3 Pot of Prosperity. 2 World Legacy Monstrosity which either Special Summons a Level 9 monster from your hand or you can target a Level 9 monster you control to Special Summon 2 Level 9 monsters from your Deck with a different Type and Attribute than that monster but with different names. You could play just the 1 copy, but I am playing 2 to have an increased chance of drawing it so that in a situation where I do draw it, I can instead search for Succession off of Ib to bring back Hot Red Abyss and use it as interruption. 1 World Legacy Succession which targets a monster in your Gy and Special Summons it to Linkpoint. 3 Resonator Call which adds a Resonator monster from Deck to hand. 1 Predapruning which targets and Special Summons a Predaplant monster from your GY and equips this card to it. And 3 Underworld Ritual of Prediction which Ritual Summons a Prediction Princess Ritual Monster from your hand or Gy face-up or face-down and you can banish it from Gy during the Standby Phase to Special Summon a non-Ritual Prediction Princess monster from Deck.
Extra Deck: 1 Master of Ham which Special Summons a Flip Monster from hand or Deck on Fusion Summon. 1 Predaplant Ambulomelides which adds a Predap card on Fusion Summon and can target and Tribute a monster to Special Summon a Predaplant monster from your Deck. 1 Ultimaya Tzolkin which cannot be Synchro Summoned and can only be Special Summoned from Extra Deck by sending 2 Level 5 or higher monsters you control with the same Level including a Tuner and a non-Tuner to the GY. As a soft once per turn, when a Spell/Trap(s) is set on your field, you can Special Summon a Power Tool Synchro Monster or a Level 7 or 8 Dragon Synchro Monster from your Extra Deck. The monster we are using Tzolkin to get is Scarred Dragon Archfiend, but if you want more Extra Deck space, you can play Hundred Eyes Dragon instead so that you can cut Scarred and regular RDA. Also, maybe you could do something interesting with Hundred Eyes's copying effect. 1 Hot Red Dragon Archfiend Abyss. 1 Scarred Dragon Archfiend which we are using as our DARK Dragon Synchro Monster of choice to Synchro for Abyss. And if it is sent from the Monster Zone to the Gy, you can Special Summon the regular RDA from Extra Deck which gives us more Link Material. Speaking of, the 1 Red Dragon Archfiend for the effect of Scarred. 1 Shooting Riser Dragon which is a Level 7 Synchro Tuner that can send a monster with a lower Level than it from Deck to Gy to reduce its Level by the Level of the sent monster. We are using Shooting Riser as a way to access a Level 1 Tuner. 1 Ib the World Chalice Justiciar which adds a World Legacy card from Deck to hand on Synchro Summon and if it leaves the field, you can Special Summon a World Chalice monster from Deck. 1 Herald of the Arc Light which adds a Ritual Monster or Ritual Spell from Deck to hand if sent to GY. 1 Mereologic Aggregator. 1 Laevateinn, Generaider Boss of Shadows and 1 Jormungandr, Generaider Boss of Eternity. 1 Sky Striker Ace - Camellia, 1 S:P Little Knight, and 1 I:P Masquerena.
Side Deck: 2 Nibiru, the Primal Being, 3 Thunder King, the Lightningstrike Kaiju, 2 Gizmek Kaku, the Supreme Shining Sky Stag, 3 Dark Ruler No More, 2 Lightning Storm, and 3 Evenly Matched.
