Creature — Eldrazi

Devoid (This card has no color.) Haste At the beginning of each end step, if you control no other colorless creatures, return this creature to its owner's hand.

Niche aggressive creature for colorless Eldrazi strategies, but the conditional return effect severely limits its utility outside dedicated decks. Dust Stalker demands you maintain a critical mass of colorless creatures to stay on the battlefield, making it a poor fit for most red-black decks where it's easily replaced by more reliable threats like Kroxa or Anax.
