Aspect of Time

Flash, Indestructible
When Aspect of Time enters the battlefield, you may remove any creatures from combat. Untap all creatures you control.
Creatures you control gain undying (When this creature dies. if it had no +1/+1 counters on it, return it to the battlefield under it's owner's control with a +1/+1 counter on it).
If Aspect of Time is placed into a graveyard, shuffle it and your graveyard into your library.
Time is a constant observer, ever-seeing.
