Ragavan, Nimble Pilferer

Whenever Ragavan, Nimble Pilferer deals combat
damage to a player, create a Treasure token and
exile the top card of that player’s library. Until end
of turn, you may cast that card.

Dash {1}{r} (You may cast this card 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.)
