I love the fact that you are constantly improving the game. However, I believe the nerf to PJ is too much. He is now a very corner case card(very low mana and silent summoner games). Even in low mana matches he is not good anymore since almost no dragon cards are low mana. Now Camila and Selenia are better summoners with only 3 mana cost and a buff/debuff.
I think you should give him the slow ability to bring him back to relevance. Either that or raise his mana cost to 3 and retain the weaken ability.
