I have some things to say, remember this is just my opinion:
A. I think Impfinity's super is better than Neptuna's, but even then, both deserve top tier.
B: Sunburn, Terror-Former and Tater Toss aren't average, they are pretty good at any moment of the game (Except for sunburn)
C: Mush-Boom, as I always say and whine about, isn't that good, I mean, it should be buffed to 3 Damage, it isn't even that good in turn 1.
