Sire of Insanity

Symmetry that is anything but. The end-step wipe hits both players, but the player who casts a 6/4 demon on turn six has already committed their resources to the board, while the opponent is the one left scooping cards into the graveyard with nothing deployed. This is the classic hellbent payoff weaponized as a global lock: empty your own hand by curving out aggressively, then deploy this to slam the door on any control or midrange deck that wants to sit behind a grip of answers, counterspells, and removal. The discard fires every end step, not just once, so there is no rebuilding a hand while it sits in play; each turn resets both players to topdeck mode, and topdeck mode favors whoever already has the bigger thing on the table. The 6/4 body is the rest of the design: large enough to threaten a four-turn clock and end the game before the opponent draws their way back into the fight. The friction the card accepts is that it punishes its caster too, so it belongs in decks built to run dry and decks that turn an emptied hand into a clock rather than a liability. Against combo and storm it is a hand-stripping clock; against grindy decks it inverts the entire premise of holding cards.
