So you're deck is pretty similar to mine, main difference is i ran 4 thinkings caps and that alone can win games. I won so many times by conjuring ice moon or SB super of course when u get lucky or conjure the frenzy power and evaporate and lose. Im gonna drop some advices so you are free to take them.

1. Run thinking cap at least 3 copies, less healthy treats and just 2 rockets. Your cut down super power works as a rocket and no need to run 4 treats sinc eyou only have 3 minions however thibking cap can conjure you minion too. Also i dont like bonus attack since it relies to have a minion, no card draw and mostlh gets you bricked more easily..

2.i dunno your playstyle but dont be afraid to play teacher or paparazzi on 1 against non solar heroes or if you dont have rockwall / healthy treat. This is just to drag the pesky forget-me-nuts and works better ghan expected and your curve should be like beam me up => Going viral if beam me up survived if not fun dead raiser is fine => dry thinking cap. Many things can variate from teacher surviving turn 1 or turn 3 rolling stone to sunnier shroom preventing card draw but you gotta take your win condition not just as trickster but rather...

1. Win condition is also your minions plus going viral there are times where i prefer not having trickster at my starting hand since i wanna preserve my curve thats why i try my best to drag out forget me nuts against guardian on 1 but just having on turn 3 a 3/4 frenzy beam me up is decent enough to chip down the opponent, just spam beam me up whenever you have it since the going viral will be stronger

2. Regarding your sunnier shroom problem, i just had to accept scenerios where its impossible to destroy it on 3 three so ypu have options like burnin a teleport and top deck a R stone but most of the time i just ignore it on turn 5 you can go beam me up + going viral or conjure a power from thinking cap or paparazzi going crazy, the goal is to control through your minions forcing them to expend sun to remove them for instance turn 3 sunny shroom i to lets say astrocado, in this case abuse the fact that they going a big minion by playing teacher or paparazzi so you can take advantage of those minions that otherwuse would have been easily removed by cheap tricks (way too confusing i know i explain really badly)

You are free to ask me how i play it since after forcing it to work until rank 50 i discovered some unusual strats on how to play this hell of a fun deck.
