Sweettooth Witch

The Food token has spent most of its life as a lifegain byproduct: something incidental you make, hold, and occasionally cash in for three life when the game slows down. This flips the resource into a weapon. The enters trigger stocks a Food, and the sacrifice ability turns any Food (that one, or any you already had lying around) into two life lost by a target player. The conversion is the whole pitch: a Food is worth three life to you when eaten normally, but this reroutes it into two life drained from an opponent, and because it drains rather than deals damage, it walks past fog effects and damage prevention that a red closer would run into. It also does the reaching a black deck built on artifact tokens usually cannot: retiring the last few points of a life total without a creature connecting. The 3/2 body is almost beside the point, though it is a serviceable enough clock to keep the sacrifice ability from being the only pressure. What makes this a build-around rather than a role-player is that it does not care where the Food comes from. Any generator that keeps the board stocked with tokens becomes a drain outlet the moment this is in play, and the two-mana price per activation is the only governor on how fast that outlet empties an opponent out.
