Battle - Encounter
(As an Encounter enters, choose an opponent to protect it. You and others can attack it. When defense counters are removed, create a 0/0 Army token if you don't control one, then put that many +1/+1 counters on a Army you control.)
When Avaz Rising enters, return target creature card from your graveyard to the battlefield. That creature becomes an Army in addition to its other types.
