Argore, Howling Paragon

When you cast your second creature spell each
turn, reveal cards from the top of your library
until you reveal a creature card. Put that card
into your hand and the rest on the bottom of
your library in a random order.
Battle Cry (Whenever this creature attacks, each
other attacking creature gets +1/+0 until end of
turn.)
