Mr. Gabriel

Split Second. Shroud.
When Mr. Gabriel enters the battlefield, exile
any number of instant, sorcery, or noncreature permanents from graveyards and or your hand.
Once each turn, you can play a spell exiled this
way without paying its mana cost, and you may
play that spell as if it had flash. You can't play
spells or lands that aren't in exile.
Yes, his final item.
