How do you win this BOSS BATTLE?

[JedTheRealFish]

I failed to get screen shots of the most hopeless one --- Green Shadow against Impfinity, Impfinity  starting with 25 health and three imps, the first trick being the two extra 2-1 imps, the second turn with the toxic waste imp --- it was really something to see. The entire screen full of toxic imps twenty seconds into the game. 

My question is: how do you beat this AI plant mission game? I can't find any videos of it? 🌱

Kabloom hero, preferably Solar Flare, having both Sunburn and Berry Blast, is good for taking out 1 health imps/toxic waste imps if you're lucky on the initial draw
