You can send monotypes too >:Y

I’m thinking one artillery-based

It starts as a pure fire: An armless bipedal poké with a stubby tail it uses to brace itself when firing fireballs from it’s mouth. It has high Sp. Attack but also a new ability that always makes it take recoil damage.

Then when traded holding a Metal Coat It becomes clad in iron and gains Reckless or Rock Head, and can learn a new special fire move with recoil damage. Cuz come on I wanna see recoil on special moves >:Y
