Auroth'nymjor

Flash
Flying
When you cast Auroth'nymjor, exile target spell, creature, artifact, enchantment, or planeswalker, until the end of it's controller's next end step. If a spell was exiled this way, you may cast that spell until the end of your next turn, and spend mana to cast that spell as if it were any color.
When you cast an instant or sorcery spell, tap target non-land permanent. It doesn't untap during it's controller's next untap step.
