Juniper still persists, #1: Absolver Thrull

Imprint — , : You may exile an instant or sorcery card with mana value X from your hand. At the beginning of your upkeep, you may copy a card exiled with this artifact. If you do, you may cast the copy without paying its mana cost.

Haunt (When this creature dies, exile it haunting target creature.) When this creature enters or the creature it haunts dies, destroy target enchantment.

Whenever another creature you control enters, put a +1/+1 counter on that creature and a +1/+1 counter on this creature.

Sacrifice a creature: Target player mills cards equal to the sacrificed creature's power.

Choose any number of target creatures. Each of those creatures gains persist until end of turn. (When it dies, if it had no -1/-1 counters on it, return it to the battlefield under its owner's control with a -1/-1 counter on it.)
