The errors in Retro's post. It's messed everything up. We've gone from the chosen trinity, your holey trinity, and chair's whatever. It's been anarchy.
My current scheme:
Charizard: Use some green stuff to make a long neck, keep the wings and have it breathe fire.
Blastoise: Get some carapaces from a different model to fashion into a shell. The daemon comes with a combination of weird "cannons" on the back which are perfect for Blastoise.
Venusaur: I'm going to have to sculp pretty much the entire flower myself. And have one combination of long fingers representing the vine whip.
The initial battle plan is having Charizard flying using flamethrower on Venusaur who is using a tree to block the attack whilst using it's vine whip fingers on Blastoise who is firing a hyrdo cannon up at the Charizard. It's going to be tough creating the landscape to go with it. But I'm down with the complicated shit.
And it's pedantic.
