Featherwyrm's Descent

Vanishing 3 (This permanent enters the battlefield with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
Whenever Featherwyrm's Descent is put into
a graveyard from play, put a 6/6 white Dragon creature token with flying named Holywing Dragon onto the battlefield under your control.
