Billowing Shriekmass (FDN)

Creature — Spirit

Flying When this creature enters, mill three cards. (Put the top three cards of your library into your graveyard.) Threshold — This creature gets +2/+1 as long as there are seven or more cards in your graveyard.

Niche graveyard filler for self-mill strategies, but the modest body and conditional power boost make it easily outclassed by more efficient mill creatures and payoffs in formats where threshold decks exist.

Foundations — Uncommon
