also, do you think 13 starting life is good, or should i change it to 14 or 15?
Statistically at 13 life your Priestess will kill in 2 turns of attacks. Your Beastmaster in 1. Your Warlock in 2. Your Wizard in 3.
Wizard is still pretty weak comparatively and the Priestess is very strong. Knight of Westlock supported by Hand of Bim-Shalla trumps everything else on the list. Warlock has the best shot against it with Agony but Priestess can remove conditions and also has 3 healing spells. Granted a new player may not realize the synergy and utilize the advantage. If the Beastmaster knows to stay back and summon the foxes he can Call of the Wild and kill the enemy mage in a single round. So either the Priestess and the Beastmaster need a nerf or the other two need a buff. More HP would reduce the whoever strikes first wins nature of this variant.
Would be hard to make what is essentially a 5 minute demonstration of basic mechanics competitive.
