Gravelord Nito

When Gravelord Nito enters the battlefield, for
each creature in all graveyards, create a 2/2 black
skeleton creature token. If that creature is
legendary, create a 4/4 black giant skeleton
creature token instead.
Wither
{t}: Gravelord Nito deals 1 damage to target.
Whenever a skeleton not named Gravelord Nito
dies, create a token that is a copy of that creature
on the battlefield tapped under your control.
