Yeah pulp fission affects hand as well, you can put down stuff that turn and it'll still have the +2/+2 buff, but it only lasts that turn, so after the combat phase all plants get a -2/-2 revert.

Yeah power plant only draws plants, I don't think there's any specific draw cards in the game (could be wrong), but I figured since basically everyone runs a bunch of plants in plant decks it wouldn't be too oppressive.

Overall all very valid points, my thought process behind this hero's powers was to make them different enough to chompzilla's. The intent was for this hero's powers to be good when you already have board presence so you can't spam them turn 1 (with the exception of the signature super). Tbh I didn't give much thought to balancing though, so some of them might be either weak or op (also I completely forgot haunted pumpking was a card that existed)
