I'm currently using:
Morty (HP 270), Rainbow Shirt (HP 396), Host (HP 358), The One True (HP 374) and Morticia (HP 352).
Morty is currently ATK/DEF 1200/1200ish
Rainbow Shirt, Host and The One True are all ATK/DEF 600/600ish
Morticia she's HP 352 ATK 429, DEF 899-- she's the wild morty wrangler, hence the disparity to prevent accidental dazing
