Atima, Mother of All

Flying, defender, indestructible
At the beginning of your upkeep, sacrifice Atima
unless you pay {w}{u}{b}{r}{g}.
Creatures you control have all names of creature
cards. The same is true for creature spells
you control and creature cards you own that aren't
on the battlefield.
The "legend rule" doesn't apply to creatures you
control.
The first beginning. Celebrate for the imperfect.
