Most versions of Mitosis makes FGs easy. For instance: Mitosis scarabs. Tons of HP, eats ev erything, gets lots of damage due to it.
Must have missed that deck, altogether with the tests? Mitosis scarabs had to be nerfed a bit to prevent pharaoh becoming useless, imho...most mitosis decks i read about SEEMED to be strong against FGs, but in the end i never heard of any deck, coming even close to that magic 50% winning ratio (e.g. staffosis)...but maybe you give a link to a build, where FGs become easy. That would be great, as mitosis will probably make it into the game.
The nerf about not targeting weapons had to come...its a pity (loved that decks), but understandable...
Concerning PvP: Hard to balance that in advance? Time has to tell?
Edit: voted for no weapon targetting, cost increase by 1...old version was just a bit to cheap, imho...
