Miss Alenna Fortune

Menace, haste
Whenever Miss Alena Fortune deals combat damage to a player, you may exile the top card of target player's library. If you do, create a number of colorless Treasure artifact tokens with "{t}, Sacrifice this artifact: Add one mana of any color to your mana pool." equal to the converted mana cost of the exiled card.
