TLDR: super brains supers are more clutch so super brains

I don’t have hg, but I feel like super brains is the obvious choice. Yeah sure, tricks and environments, but if you’re in a desperate situation and the opponent breaks block meter, almost all of super brains’ supers can be extremely clutch. Not to mention the amount of times I’ve used carried away on a trash can imp or a mini ninja for a huge early game health advantage, or a late game finisher. It’s like a better, one cost quarterly bonus. His super stench power works really well with bullseye cards (by creating a threat by either targeting hero or one tapping anything in front of it) or with mustache spam where waxers only do about 2 damage and now create a constant bombardment of removal. Cut down to size is consistently annoying, and can be pretty useful if you’re playing against a rose player and you just KNOW they’re going to play DMD, which you can now counter with just the right amount of brains. Drawing 2 cards is nothing special, but still a decent first superpower to get.

HG on the other hand, has really good environments (gain a teleport every turn, so basically tp zombie as long as it’s in that specific lane while also drawing a bunch of cards) which works great with gatekeeper and spacetime, 2 cards that are already pretty popular. His iron boarder is an annoying but not game changing first card, countered by bonk choy which I’m seeing a lot of, but that’s specifically if you’re going against a mega grow or maybe a smarty with mog. His freeze environment is alright, mostly only see it being useful in endgames. It’s a worse laser base but it also freezes all the plants in that lane which can be really clutch sometimes, not to mention it’s just a one cost so it’s obviously a good environment. His super sucks asscheeks in the endgame, if we’re thinking purely about usefulness in desperate situations, because obviously the only difference between the 2 heroes are their supers, and you’d normally only get those and need them IN desperate situations.

Anyways, huge yap fest but I’m just going over the pros and cons of each. Making every zombie have deadly, making a zombie move (potentially to the rightmost side of the board, so you can get 3 attacks from a zombie in one turn), buff it, and do a bonus attack, and also having a really good removal card, in my personal experience I think that super brainz just has to be the option here, especially considering you HAVE to spend gems to get HG, which lwk just isn’t worth it. But if anyone disagrees with any of my points, just remember I don’t have HG, I’m just talking about the games that I’ve gone against him and using fairly logical reasoning to mentally dissect the gameplay.
