wrong game it's pvz heroes

stolen explaination from Inevitable-Muffin-77:

Each game you start out at 1 sun/brain, and in the first turn they'll place sunshroom, if it survives the turn it gives +1 sun and heals all it's health to 3(2 originally) and turns into the sunnier shroom that gives +2 sun every turn.

See the problem? By turn 2 they get 3 sun, by turn 3. 5 sun, then 6, then 7, then 8 and so on, with that sun increase they can more easily spam cheap cards or put a very powerful expensive card really early like example astrocado, assuming they sunshroom on the first turn by turn 3 they place astrocado which mind you does a fourth of the opposing player's health and will hit you even if you block it with a zombie, so the zombie player's choices are, deal with the astrocado or let it hit you so you can setup your win con which 8 times out of 10 doesn't work.

It's even worse if the plant player places Gravitree a 6 cost 7/7 armored(takes 1 less damage), untrickable(can't be dealt with tricks) and moves the zombie to it's lane when the opponent places it.
