Ragavan, Nimble Pilferer

Whenever Ragavan, Nimble Pilferer deals combat damage to a player, create a tapped and exerted Treasure token and exile the top card of that
player's library. Until end of turn, you may cast
that card.
Dash {r}{r} (You may cast this spell for its dash cost. If you do, it gains haste, and it’s returned from the battlefield to its owner’s hand at the beginning of the next end step.)
