Cloud, Stoic Doyen

Creatures you control get +1/+0 for each creature in
your party. (Your party consists of up to one each of Cleric, Rogue, Warrior, and Wizard.)
At the beginning of combat on your turn, if you
have a full party, you may search your library for an Equipment card, put it onto the battlefield, attach it
to a creature you control, then shuffle.
