I was considering doing some sort of Sacred Beast thing with Lady of Lament when I saw Three-Eyed Ghost and realized how it could search Raviel, Lord of Phantasms and Raviel, Lord of Phantasms - Shimmering Scraper, but as it turns out that the only benefit to playing Raviel and Shimmering Scraper is making use of Lair of Darkness for Raviel's ATK-gaining effect by Tributing a monster and Shimmering Scraper adding itself back by Tributing a monster in addition to their big ATK stats and OTK potential via Shimmering Scraper targeting Raviel. On the other hand, Uria, Lord of Searing Flames functionally has similar, if not better OTK potential while also giving you the ability to make better use of Hyper Blaze rather than having to rely on 2 hard-to-summon monsters. This Deck intends to use cards like Dark Beckoning Beast and Opening of the Spirit Gates to get you a Chaos Core on the field, which gives you a Level 3 DARK Fiend Target for Ties of the Brethren while also allowing you to set up a Uria OTK with Hyper Blaze on your following turn or a bit later.
For monsters: 3 Lord of the Heavenly Prison which can reveal itself in hand to give all of your Set cards destruction protection, and if you activate a set Spell/Trap from hand, and if it was revealed already, you can set a Spell/Trap from Deck. First off, giving protection to your backrow is already such a good effect, but in this Deck, specifically, since we want to try to OTK with Uria on your following turn, Lord can set Hyper Blaze from your Deck to set-up the OTK for your following turn. 1 Uria, Lord of Searing Flames. It needs to be Specialed from hand by sending 3 face-up Traps you control to grave and gains 1000 ATK for each Continuous Trap in your GY, and it can destroy a set Spell/Trap every turn. You are never hard-Summoning this card. We are usually getting this out from GY with Hyper Blaze ignoring its Summoning Conditions. 3 Lilith, Lady of Lament which can Tribute a monster to have your opponent choose 1 of 3 Normal Traps of your choice to set from Deck. 3 Alice, Lady of Lament which can Summon back a Lady of Lament from GY on Normal Summon, it can banish a Trap from hand or GY to Special itself from hand, and if it's Tributed, it can add a Fiend whose ATK and DEF equals 2000 when combined which gives you access to Lilith for next turn. 1 Chaos Core. It is a bit of a strange card as it is essentially pretty bad, even though it was released in 2020 in the Sacred Beast Structure Deck. It essentially is supposed to set-up Dimension Fusion Destruction as it sends up to 1 each of Raviel, Hamon, and Uria from hand and/or Deck to GY if its targeted by an attack or effect to place a Phantasm Counter on itself for each which prevents battle damage and prevents it from being destroyed. However, it has a different use in this Deck. For 1, it is a Level 3 DARK Fiend target for Ties of the Brethren on field. Since Beckoning Beast gives you an extra normal for this card, you can Link them off for a Link-2 and Summon back Chaos Core with Spirit Gates, giving you a Level 3 DARK Fiend on field with a Link-2 for more interaction and/or interruption on your opponent's turn. Also, since Ties targets Chaos Core, it can send a Uria from Deck to put it into rotation for Hyper Blaze to bring it back next turn. 3 Dark Beckoning Beast which adds a Uria, Hamon, or Raviel or a card that mentions one of them from your Deck on Normal Summon. Also, it gives you an extra Normal of a Fiend with 0 ATK and DEF. Again, this gives you access to Chaos Core on field for a Link play for Spirit Gates to bring back Chaos Core. Finally, 1 Tour Guide From the Underworld for an Xyz play in a tight spot.
For Spell/Traps: 3 Opening of the Spirit Gates. On activation, it searches Uria, Hamon, or Raviel or a monster that mentions one of them from Deck. As a soft OPT, it can discard a card to Special Summon a Fiend from GY with 0 ATK and DEF. This gets you back Chaos Core after a Link play for a target on field for Ties, of course. And it's third effect adds back a Continuous Spell from GY if you control a Level 10 monster which is not relevant in this Deck. 3 Ties of the Brethren which Summons 2 monsters from Deck with the same Type, Attribute, and Level as a targeted monster you control. 3 Pot of Prosperity. 3 Transaction Rollback which pays half your Life Points to copy the effect of a Normal Trap in your opponent's GY and can banish itself from GY and pay half to copy the effect of a Normal Trap in your GY. Because Spirit Gates discards to bring back a Fiend, it give you the opportunity to discard Transaction Rollback to have access to its GY effect which is much better in this Deck. The same goes for Hyper Blaze's effect to discard a card to bring back a Sacred Beast. 3 Archfiend's Ghastly Glitch which targets a card on field and destroys it if you control a Fiend and gives you the option of sending a Fiend from Deck to GY afterwards. 1 Trap Trick. 3 Infinite Impermanence. 1 Dimensional Barrier. 3 Torrential Tribute. 2 Hyper Blaze which makes Uria's Summoning Conditions able to send face-down Traps you control. Also, once per battle, it can send a Trap from hand or Deck to the GY to make the ATK/DEF of a Uria you control become equal to the number of Traps on field and in GY x1000 for the rest of the turn which is great for OTKing. And it can discard a card to bring back a Sacred Beast. We will be going through plenty of Traps in a Lady of Lament Deck, and this card allows you to easily Summon Uria while also making it a great OTK tool.
Extra Deck: 1 Garura, Wings of Resonant Life, 1 Fossil Warrior Skull Knight, 2 Elder Entity N'tss, 1 Golden Cloud Beast - Malong, and 1 Mereologic Aggregator for Ultimate Slayer and Dogmatika Punishment targets. Garura draws a card, Skull Knight can banish itself from GY to destroy a monster on field, N'tss destroys a card when sent to GY, Malong bounces a face-up card your opponent controls, and Aggregator negates the effects of a face-up card your opponent controls. 1 Divine Arsenal AA-ZEUS - Sky Thunder. 1 Stellar Nemesis T-PHON - Doomsday Star. 1 D/D/D Deviser King Deus Machinex which can be made with any D/D/D monster and it can detach 2 cards when your opponent's monster card activates its effect and attaches it to this card. 1 Downerd Magician for more Zeus material. 1 D/D/D Stone King Darius which can be ranked up into Machinex or protect itself during battle for you to easily make Zeus. 1 Number 49: Fortune Tune to make Zeus, 1 Unchained Soul Lord of Yama which can be send off of Ultimate Slayer or Punishment as it can banish itself from GY when a card(s) you control is destroyed to Summon a Fiend from hand or GY. 1 S:P Little Night and 1 I:P Masquerena for your Link play options.
Side Deck: 3 Kashtira Fenrir. 1 Dinowrestler Pankratops. 3 Ultimate Slayer. 1 Simul Archfiends. 3 Evenly Matched. 2 Dogmatika Punishment. 2 Ice Dragon's Prison.
