Can you help me with the interaction between Necromancy and Yarok?
When Necromancy enters the battlefield, its ETB effect will trigger and Yarok will cause it to trigger an additional time. Each trigger can target a different creature card in a graveyard and each trigger will return its target to the battlefield under your control. Necromancy will end up as an aura attached to the target of the trigger that resolved last, but the first creature will be just fine without Necromancy attached to it, so long as Necromancy is still on the battlefield. When Necromancy leaves the battlefield, both of the creatures it returned to the battlefield will be sacrificed, if any of the are still on the battlefield.
