Captain Flint, pirate legend

Whenever Captain Flint 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.)
