>>21559391Not the same guy, but here goes...
Greninja as Water Fighting
Delphos as Fire Flying (Say it rides a broomstick or something)
Chestnaught as Grass Rock.
Alternatively, use a different triangle since the Fire/Grass/Water one is played out.
Have one start as pure flying and become Flying/Water
Have one start as Fighting and become Fighting Electric
Have one start as Rock and become Rock Ground. It can still break the triangle because the Electric/Fighting one is a glass cannon and the Rock guy's ability is Sturdy. Oh yeah, they don't get those boring blaze/torrent/overgrow abilities. Give them something more interesting.
