When Patriarch is deployed, at the end of turn, all beasts you control gain +1/+1.
Surge of the Wild
2 + x Cost
When you play Surge of the Wild, you may pay an additional 2, 4, or 6 resources. For every 2 resources you pay upon using Surge of the Wild, beasts you control gain +1/+1 until the end of turn.
(ie, for 2, beasts you control gain +1/+1, for 4, beasts you control gain +2/+2, etc)
Protector of the Young
Creature - Beast
When Protector of the Young is deployed, when a beast you control would take damage this turn, all damage is redirected to Protector of the Young instead.
Until the end of this turn, the first time a beast under your control would die, it instead survives with 1 hp. (AKA, AoE primal rage for beasts)
Cannot be killed by non-damage sources
When Retreating Hulker enters the deployed zone, target creature loses half of it's attack power until the end of the turn.
Pay 2: Retreating Hulker returns to controlling player's hand (preemptive).
Just some ideas. Right now there is literally no reason to play 3p WP over 2p WP hermit. 3p WP needs a lot of tools, particularly at 4 cost, to both improve the utility and capabilities of the faction as well as smooth out the WP curve so there are actually good moves to make at 4 resources.
