Veridia, Lord of the Circle

Deathtouch, menace

Whenever Veridia attacks, for each attacking
non-Beast or non-Zombie creature you control, look
at the top six cards of your library. You may put a Beast or Zombie creature card from among them
onto the battlefield tapped and attacking. It gains indestructible until end of turn. Put the rest of the cards on the bottom of your library in a random order.
