Kat B320

Hexproof, Reach

Tech Support - As long as Kat B-320 is on the battlefield, creatures you control have Hexproof and you have no maximum hand size. When Kat B-320 dies, discard down to seven cards. You may play a card discarded this way without paying its mana cost. Put the rest on top of your library in a random order.
