Laval w/ Plants

Before anyone says anything, I know there isn't much of a Plant engine. Just tell me what you think, and I'll be certain to make corrections if they make enough sense. Thank you.

where is the laval card to dump 2 lavals to the grave, it is a must D:

Sweltering Heat Transmission Field is a must.

And 4 cards added = Plant Engine?

Anyways, what German said. Although the deck would probably run better without the Plant "Engine".
