Raven-H

Salvage 1 (When Raven-H enters the battlefield,
Raven-H may salvage a card from your graveyard by exiling it)
If Raven-H salvaged a creature card, tap target creature an opponent controls. That creature
doesn't untap during its controller's next untap
step.
If Raven-H salvaged a non-creature card, return
that card to your hand instead of exiling it.
