Icenaroth, Vengeance Cheeks

Trample, Menace
When Icenaroth, Vengeance Cheeks enters the battlefield, it deals 2 damage to each creature with flying.
For each creature dealt damage this way that dies, create a Nut token.
Nut tokens are colorless artifact tokens with:
“ {t}, Sacrifice this artifact: Add one mana of any color. Spend this mana only to cast creature or Equipment spells.”

{2}: Target creature you control gets +2/+0 until end of turn. If it's a Squirrel, it gains indestructible until end of turn.
