Main Deck
Uria, Lord of Searing Flames is the main idea behind this deck and the main wincon , beeing able to OTK with Hyper Blaze helping it reach huge ATK and resummoning it every turn if you summoned it properly the first time.
Awakening of the Sacred Beasts helps you stay healthy if Uria, Lord of Searing Flames is on the field and also recover a continious trap every turn.
Dark Beckoning Beast is your sacred beast engine searcher , with a single Opening of the Spirit Gates to help you get another copy of Dark Beckoning Beast on the hand and then summon it with its secondary effect to turn it into something more usefull like Akashic Magician and then Knightmare Unicorn .
A single Dark Summoning Beast in case you need Uria on the field and have no way to get 3 traps on the field.
Solemn Judgment as a negate for spell and traps mainly as you dont have many ways to deal with them , but also helps as a summon negation if needed.
Fiendish Golem at 2 because its searchable by the resonator/archfiend engine , it is recoverable from graveyard by Crimson Gaia , so its reusable for long games , and recoverable if used as material for Uria, Lord of Searing Flames .
Fiendish Chain is a continious trap so its easier to stay on fiend to use for Uria, Lord of Searing Flames , and it is recoverable by Fiendish Golem .
Red Reign is a field wipe that is also recoverable from graveyard by its own effect after summoning a synchro monster.
A usual endboard by the resonator/archfiend engine is Red Supernova Dragon and Red Zone at least , and to reach it you need minimum one Crimson Resonator , Bone Archfiend and 2 resonators whose levels equal 4 combined, for this we chose Red Resonator and Vision Resonator , one of each is enough, but we play an extra Vision Resonator in case you need to use it as searcher for cards by sending it to graveyard by Bone Archfiend effect or Foolish Burial .
The one card combo to Red Supernova Dragon is , summon Soul Resonator , search for Bone Archfiend , special summon Bone Archfiend using its own effect , use Bone Archfiend effect to send Crimson Resonator from deck to graveyard to decrease its level to 3, go to Red Rising Dragon , use its effect to special summon Crimson Resonator from graveyard to field , use Crimson Resonator effect to special summon 2 resonators from deck/hand to field , special summon Vision Resonator and Red Resonator , gain life from Red Resonator , go to Red Supernova Dragon , get a search from Vision Resonator , search for Crimson Gaia , use it to search for Red Zone set , pass.
For that reason we play a full playset of Resonator Engine and Crimson Gaia to search for Soul Resonator .
Ash Blossom & Joyous Spring and Infinite Impermanence for handtraps.
Side Deck
Herald of the Abyss and Cosmic Cyclone are boardbreakers for hard to deal with monstes/traps respectively.
Powersink Stone is a good floodgate that doesnt hinder you as much if you play it smart , you can trim on the resonator/archfiend engine to use it since you wont be able to reach high level synchros under it , going up to the lv8 ones is enough to have your Fiendish Golem , Red Reign and -red zone effects live.
Ferret Flames are great to deal with hard to remove threats on a spell speed 2.
Terrors of the Overroot are good to interupt your opponent's field and graveyard.
