Jason Bright, Glowing Prophet

The draw condition here is doing something quietly clever: it fires only when the dead creature's power differs from its printed base power, which turns the sacrifice ability below it into a self-feeding engine. The activated ability puts a +1/+1 counter on a creature and hands it flying, then that pumped Zombie or Mutant becomes the ideal thing to feed to the next sacrifice: its power no longer matches its base, so its death cashes out a card. Most aristocrat payoffs reward the death itself; this one instead rewards having touched the creature first, which is a subtler trigger than the wording suggests and asks you to route counters and buffs through your fodder before it dies rather than treating everything as interchangeable bodies. Buffs from any source count, not just the printed activation, so anything that has modified a Zombie or Mutant's power (counters, pumps, anthem effects that grant a static bonus) satisfies the condition on death. The counter-and-flying half also gives the deck a way to convert a stalled ground board into evasive damage while stockpiling triggers, so the sacrifice cost is rarely wasted tempo. It is a build-around that punishes autopilot sacrificing and pays out to a player who tracks which of their creatures are currently larger than they were printed to be.
