Savior of Dynasties

Ascension 3 (When this creature enters the battlefield, put 3 ascension counters on it. At the beginning of your upkeep, remove one of these counters. If you can't, this creature ascends, permanently becoming an Ascended in addition to its other types)
When Savior of Dynasties ascends, choose a creature type. Return all creatures of that type from your graveyard to the battlefield, then put
a +1/+1 counter on Savior of Dynasties for each creature returned that way.
