Etali Primal Conqueror

Trample

When Etali, Primal Conqueror enters, each player
exiles cards from the top of their library until they
exile a nonland card. You may cast any number of
spells from among the nonland cards exiled this
way without paying their mana costs.

9 {p/g}: Transform Etali. Activate only as a sorcery.
