Undead Alchemist

Mill as a Zombie engine, not a clock. The first ability rewires what your Zombies do in combat: instead of subtracting from a life total, connecting damage shaves cards from the library, which means the whole win condition runs through the deck rather than the player. The second ability is where the deckbuilding pivot lives. Every creature card that lands in an opponent's graveyard (from any source of milling, not just combat) gets exiled and replaced with a 2/2 Zombie under your control, so the more you mill, the bigger your board grows. That feedback loop is the trick: an opponent's library becomes fuel, and their creatures convert into your attackers, which then mill more cards on the next swing. The 4/2 body is fragile enough that the card wants protection or backup rather than to win combat on its own, but the mill conversion turns even a single connection into a swing in card advantage and board presence at once. It is a design that asks you to commit fully to a single axis: lean hard into Zombie tribal and into self-reinforcing mill, and the two halves stop feeling like separate abilities and start feeding each other.
