Yamato

{7} Equip: Target creature gets +1/+1 First strike, Hexproof and Oblivion (Whenever this creature is blocked target creature is exiled.) Whenever a creature equipped with Yamato deals damage to a player that player loses the game.
This blade is not for the faint of heart. If used incorrectly the very planes themselves could vanish into nothing. In my hands this blade can cut the very existence of whoever stands before me into nothing.
