Whenever another Scarecrow you control enters, destroy target permanent.
Reaper King leads a five-color Scarecrow tribal deck that pumps your artifact creatures and turns every Scarecrow that enters into a Vindicate, blowing up a permanent each time. You ramp into the King (his hybrid cost makes him castable for as little as 5), then flood the board with Scarecrows—many of which are colorless artifacts that fit any deck—to grind opponents' boards to dust while building a wide, buffed army.
Five-color identity gives access to the best removal, ramp, and tutors in the format
Every Scarecrow ETB is a free permanent destruction trigger—incredible incremental board control
Hybrid mana cost makes him surprisingly cheap and re-castable after removal
Scarecrows are colorless artifacts, enabling artifact synergies and recursion
Anthem effect makes a wide token board genuinely threatening
Scarecrow tribe is shallow and many members are weak vanilla bodies
Relies on the commander to enable the payoff—removal slows you significantly
Five-color manabase is expensive and can stumble without good fixing
Slow to close games; can durdle without a dedicated finisher
Vulnerable to board wipes that erase your token investment
