Prince Morcar, Undead Bane

Boss Horsemanship (This creature can attack a boss permanent and can't be dealt damage while attacking)
If Prince Gon of the Statues enters the battlefield or on the battlefield gain control of it and instead of making players creatures statues you may turn boss permanents into 7/7 statue tokens with "Can't Block" and minion permanents become 2/2 statue tokens with "at each players end step deal 3 damage to that player".
