Odunos River Trawler

The body is incidental; the engine is a graveyard relationship with a card type black has no native business touching. The casting cost is mono-black, but the activated ability demands a white pip to fire, and that color split is the point: this is a black creature engineered to feed a white enchantment-creature shell. One body delivers two retrievals of the same narrow effect, one passive on entry and one on demand via sacrifice, both pointed at returning a god, a bestow creature, or an aura-creature from the yard. The sacrifice clause is the clever part of the loop: the card that rebuys your fragile threat can itself become the sacrifice fodder, so a creature you replay or blink keeps generating recursion while doubling as outlet material. Constellation and enchantment-creature strategies lived and died on resilience, and this was built as their workhorse, the support piece that quietly rebuilds a board of permanents rather than the flashy threat sitting on top of it. The Zombie type and the 2/2 stats are filler around a recursion package that asks you to have an enchantment-creature graveyard worth dipping into; without that, you are paying three mana for a vanilla body and a dead ability. It is a niche tool by design, a cross-color bridge meant to keep a specific tribe of permanents coming back rather than to do anything on its own.
