Kalisa Blackwater

Whenever a Pirate you control deals combat
damage to a player, that player is under siege.
(That player creates a Siege emblem with: "At the beginning of your upkeep, sacrifice a Food or lose 2
life." and "{4}, Sacrifice this emblem: Target opponent
draws a card.")
At the beginning of your upkeep, create a
Treasure token for each Siege emblem your
opponents have. (It's an artifact with "{t}, Sacrifice
this artifact: Add one mana of any color.")
