Etali, Primal Conqueror (MOM #298)

Trample

When Etali 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}{G/P}: Transform Etali. Activate only as a sorcery.

Trample, indestructible

Whenever Etali deals combat damage to a player, they get that many poison counters. (A player with ten or more poison counters loses the game.)
