Iä! Shub-Niggurath!

Destroy all creatures with power 4 or less. If you destroy 3 or more creatures in this way, search
your library, graveyard, and exile for a card
named Dark Young and put it on the battlefield.
If you destroy 6 or more creatures in this way,
also create a token that's a copy of Dark Young
for each additional 3 creatures destroyed in this
way.
"Hahaha! A new record! I don't believe anyone has
ever summoned 5 Dark Young before!" - Ainz Ooal
Gown during the Katze Plains Massacre.
