IMO,he's too stronk. a magic ball which can spawn semi-homing birds. a magic orb which can deny projectile and turn then into various decoys. a magic card with can give him health.
One of the worst things about him is the "bird attack when it hits directly", I'm not entirely sure, but can the birds be shot down?
But yeah, that attack is quite spammable and deals pretty hefty damage, even the birds themself.
A projectile that boomerangs and goews through walls should maybe give him a bit less hp back, i rarely ever see someone use it
anyways, since the primary is used most of the time.
