Gravelord Nito

Whenever Gravelord Nito enters, create three 2/2 black Skeleton creature tokens.

At the beginning of your End Step, you may sacrifice a creature. When you do, mill cards equal
to that creature's power and then return any creature or land from your graveyard to your hand.
If you are Cursed, you may target any permanent
in your graveyard and put it onto the battlefield instead.
