Flying, menace
Whenever this card deals combat damage to
a player or planeswalker, create a 1/1 colorless
Abyss Minion creature token for every 1 damage
dealt.
Whenever another creature you control is dealt damage, roll a 20-sided die: a random player mills
cards from the top of their library equal to the
result. This ability only activates once each turn.
