my favourite deck ! RANDOMNESS !

@XMylezX again, as i mentioned many times before , that EXACT deck has that way, the cheap cards are only for execution and preparing your ground, the deck is meant to take damage as you can take and heal yourself,  so cheap plants that dies instantly are no "long term" plans at all.. i even think if you are not mega-grow or guardian hero, one cost plants aka weak plants will rarely help you develop anything useful or for long term AT ALL ( except beans for sure )

as an example for your deck, i hope you won't bother if i analysed it in my opinion, i hope you will be open to discussion about it
for solar flare i'm absolutely good and i kinda suck at the rest, so i sticked to it and i rarely play any other hero, i've tried every known and unknown strategy with this hero, so i can tell you :-

- you are probably playing an aggressive fast win strategy

- how could you have all of these non growing, low health & attack plants and DON'T have pineclones !! 4 PINECLONES !

- you don't have pineclones, and you don't have molekale , these plants will remain weak, and in the other hand you have two of a very expensive preparation environment ( pair paradise ) what would you put there ?! astro-shroom? kernel pult ? not worth it

- why are are you making that much sun while 85% of your deck costs less than 4 or 4 ?!! and you still don't have pineclones

- blooming heart is the WORST event card in the whole game and you have 4 ! bro, i even don't have a one, i recycled them all, i mean.. solar flare is not a guardian , how could you protect it or increase it's  health ? you are given +1 attack every turn but this is gonna die anyway after 1 or two turn !!

- primal sunflower isn't worth that much, i crafted 3 of it and then i realised it's too overpriced as a super rare, i recycled them all and bought something else

- you are a solar class and you don't have any healing card ! no tacos? no astro vera ? no ketchup mechanic ?!! that's strange !! that's the best advantage solar class can give you as no other class has healing, ketchup mechanic is awesome and will fit perfectly at this deck, ( costs 3 , heals up to 5 , can has up to 6/6 when played )

- kernel-pult ?!! that's weird bro, if you are using this for the cob canon, you should at least have another cob canons , if you are doing it for the team-up to cob canon you can use puff-shroom better , it gives you a team-up plant too with 1/1 and costs 0 , and still can be used with gloom-shroom and pineclones perfectly

- only 2 berry blasts is few, and how could you execute garantuars ? you should put squash instead of toadstool, cheaper and takes any zombie away, sure it doesn't make a sun like toadstool but come on you don't even need suns here, and takes any zombie away not just the 4 or less 

i'd like to know more about how you use this deck, thank you for accepting my opinion in advance 😉
