Karenne the Barriermagus

At the beginning of your upkeep, place one aegis counter on up to one target permanent you control.
Permanents you control with aegis counters gain Ward {x}, where X is the number of cards in your hand.
Whenever Karenne the Barriermagus deals combat damage to a player, Karenne deals damage to that player equal to the number of cards in your hand.
