Kozfoalam

Trample, Deathtouch, Haste
When Kozfoalam enters the battlefield, each
player sacrifices all other nonland permanents
they control, discards their hand, shuffles their
graveyard into their library, and draws seven
cards. Each player may cast up to seven spells
from their hand without paying their mana
costs and as though they had flash.
Nicol Bolas smiled when he heard the first
impact tremor.
