Ashened

Ashened is a DARK Pyro archetype that needs its Field Spell, Obsidim, the Ashened City, in play before almost anything else can happen. Every monster in the archetype carries a condition that allows it to Special Summon itself from the hand only while Obsidim is active, so the deck's first priority on any given turn is finding and placing that card. Inferno of the Ashened does this directly upon activation, and Extinguishing the Ashened feeds the graveyard while recovering high-level Pyros, giving the deck two reliable routes to get the engine turning before it commits resources to the board.

Once Obsidim is live, the monsters come down in quick succession. Priestess of the Ashened City searches any Ashened card on summon, King of the Ashened City extends the board by pulling another Ashened monster from the hand or even the deck when facing a large opponent, and Hero of the Ashened City offers on-field Pyro destruction that can chain into another Obsidim placement. The continuous traps push the strategy further: Ashened to Endlessness Fusion Summons using either player's monsters as material, including Veidos the Eruption Dragon of Extinction, while its banish effect retroactively makes all of the opponent's monsters Pyro, opening them up to Embers of the Ashened and any other Pyro-targeting removal in the deck.

Shaman of the Ashened City and Rekindling the Ashened provide the graveyard and recursion loops that keep resources cycling, and Ashened for Eternity can seize an opponent's monster mid-turn and use its own ATK against its former allies. Because so much of the deck's output flows through a single Field Spell, early removal of Obsidim can slow the archetype considerably, though Obsidim itself triggers an Ashened summon from the deck if destroyed, giving the deck a built-in answer to that threat.
