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 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.)
