i'm questioning how the hell the season reset is keeping you in diamond league, and how you got to ultimate league.
cryo-brain is waste of turn 2 to get 4 brains on turn 3, while you have 3 sun.
the difference is that you might have a better chance maintaining tempo because they invested in cryo-brain in 1 turn, while you invested in some play on turn 2 as well.
cryo-brain isnt "OP!!' or anything, it's a somewhat good card, just a bit slow.
and these 1 cost tricks you speak of are powerful, indeed, if you have a strategy that invests on a single card.
and electric boogaloo and solar flare are 2 completely different heroes, electric boogaloo has some good early game aspects, but it also has the issue of being tied to a class that has terrible early game.
i mean, crazy is a support class, so it relies on damage based removal to get itself around as well as having dancing, which wont stay on the board forever.
while solar flare is a hero with a great mixture of control, aggressive play and ramp.
boogaloo's best deck atm is control, which is where you seize the board while relying on removal until you can pull out gargantuars' feast
while solar flare has pineclone, flowers, heal, and so much going for solar flare.
electric boogaloo's power benefits him in the strategy of controlling the board because he gains 3 health to keep himself in the game, while removing a small-medium threat off the board, fulfilling his board controlling agenda.
solar flare's superpower's utility comes in its ability, then its "2 damage". look, on turn 1 you very likely wont have that many impactful plays, so using your signature superpower is such a lead because it puts you on turn 3, while your opponent is still on turn 2. if you were to buff that on any side of the spectrum (in damage or ability) it'd simply be unbalanced. the power synergizes very well with most strategies solar flare follows.
while as for electric boogaloo, his ability also comes from his 2 classes, but overall, his superpower is pretty good because electric boogaloo generally suffers from very efficient removal, and late game due to being beastly.
but, healing yourself, and doing 3 damage is really helpful in those areas.
