Duston

Facing a Duston deck, an opponent finds their field increasingly cluttered with useless Level 1 Fiend monsters they never chose to summon. The archetype's central idea is not to attack directly or accumulate card advantage in the conventional sense, but to burden the opponent with Duston monsters through cards like House Duston and Diamond Duston. House Duston, when destroyed by the opponent, floods both sides of the field equally with Dustons from the hand and Deck, while Diamond Duston can revive itself to the opponent's field as a monster they cannot tribute or use as Extra Deck material. The result is an opponent staring at a board of deadweight creatures that block their own plays more than they threaten anything.

The endgame is reached through Starduston, which the deck builds toward by sending multiple Duston monsters from its own field to the Graveyard. Its ATK scales with how many were sent, and it locks the opponent out of Flip Summons, Special Summons, and Set Spell or Trap activations entirely, so an opponent buried under Dustons with no way to clear the board finds themselves effectively locked out of their strategy. The catch is that Starduston destroys itself if the Duston player controls more monsters than the opponent, so the deck must carefully balance how many Dustons it pushes across the table before committing to the lock.

Support cards such as Duston Roller and Magicalized Duston Mop keep the engine turning by searching Duston monsters when destroyed, rewarding the opponent for interacting with the deck's pieces and making disruption a double-edged proposition.
