Actually my greens suck but i rarely have to stack greens in war, 2 at most for a blue flank.
My 3 typically consist of purple, blue, red, or yellow. Most threatening blues i face are alasie or misandra but both are wing heros and i dont do cleanup.
Another downfall of gobbler, there are no blue minion heros but a lot of graves. If gobbler was purple then yes i’d use him more. But minion tank i face the most is delilah. 2nd is MN in a corner. 3rd is Santa in raids. Green isnt a strong color against any of those.
I’d probly roll with LJ and his AoE skill that would kill a lot of minions anyways and even if he dies the tile damage is still there.
