Selvala's Enforcer

Reveal the top of every library, hand a +1/+1 counter to this Elf for each nonland that flips, then watch everyone (including the people you are attacking) restock their hands. That trade is the whole tension of the mechanic it carries: the card advantage is split evenly across the table while the counters accrue to one board, so the refill you give away is the toll for a body that can arrive far larger than its printed 2/2. The variance sits outside the controller's hands, because a counter only lands per nonland revealed, meaning the final size is a referendum on how land-heavy the table's top cards happen to be at that instant. What keeps the design honest is that the growth and the giveaway are yoked: a wide multiplayer reveal both fattens the creature most and cedes the most fresh cards to opponents, so the ceiling and the cost climb together. This is a group-draw payoff built for a table rather than a duel, a species of green that thinks in terms of shared symmetry rather than pure selfish acceleration. The result reads less like a beater and more like a wager placed on the room: you fund everyone's hand to purchase a body whose stats you cannot fully see until the counters resolve.
