Maybe make remove gain an empty Mana Crystal. You get 4 manna for 3 manna it little too low. Why also get the same effect as Wild Growth on it. It would really slow down druid and warrior with ramp now.
when you are on turn 4 next turn both have 8 manna.
Nothing needs fixing because nothing is overpowered. I filter the meta stats in various ways. Ramp druid is nowhere near the top 5 archetypes whatever I try.
No they can’t. You can’t fix what is working as intended.
Problem ramp it need be slow down and manna cheat lower little it would give other classes more breathing room.
