Leo, the Littlest Eldrazi

At the beginning of your upkeep, create a 1/1 colorless Eldrazi Spawn

Whenever you sacrifice an Eldrazi Spawn or Scion, you may pay {c}. If you do, put a +1/+1 counter on Leo.

When Leo attacks, you may sacrifice 1 Eldrazi token and pay {c}{c}. If you do, target opponent exiles 1 permanent they control.

"Even the smallest among the Eldrazi can unravel worlds—if given enough time."
