Balance Changes (For Pvz heroes )

Hey is there any chance you could do the following changes 

Aloe vera: When played increase your hero's ❤️ by 10. Heal your hero for 10.

(If by any chance, could you make it 15?)

Forcefield: Plants here can't be hurt

(Cost 4 - Cost 3

Cornucopia: when played make a random plan each other lane

Could you change it to: Cornucopia: when played make a random plant each other lane that cost four or more.

Rotobaga 2-cost 2/1

Instead make it 2/3, plz?

Could you also give peaconlith "Untrickable"

And that's all, plz give me a comment on the ideas, also I have some good ideas to buff zombies, but I'll say that another day, THANKS :)
