Sludge Titan
Mill is usually printed as a clock: you win by emptying the opponent's library. This bends the keyword back on its owner, using self-mill as a card-selection engine rather than a wincon. Every time the body enters or swings, it digs five deep and lets you pull a creature and a land back to hand, so the mechanic that normally threatens an opponent's deck is here fueling your own. The trigger firing on both entry and attack is what makes it more than a one-shot: a resilient board that keeps refilling as it applies pressure, with the hybrid pips letting the six-drop land in either half of a graveyard-matters color pair. The five cards that hit the yard are not waste in Golgari; they are graveyard fuel, delve fodder, or reanimation targets, which turns the "downside" of milling yourself into the whole point. And the 6/6 trample body means the selection engine is stapled to an actual threat rather than a durdly value creature: it closes games while it churns. The tension is in the two halves of the trigger, one that stocks the graveyard and one that partially unstocks it into your hand, letting you decide each turn whether the pile in front of you is a resource or a road to the pieces you need.
