Once you get a few traits or gems its S2 all over again.
Wallflower + Fan Dance traits. Critter with guardian force gem defend: 10 free casts. Now insert your most broken spells like glory, mana drain, all the debuffs, and hell throw a bunch of damage at em while youre at it.
All of that brokeness fits on 1 creature with 1 artifact. You still have 5 other slots to make this setup even more broken… its rediculous and that happens with the starter creatures / cores.
SOLUTION: Auto casts cost the full mana value OR auto cast cap of 1-2 per turn.
or better yet delete the offending traits and spells. Glory never should have made it out of S2.
