Goro-themed team
>Morpeko, a two-faced rodent with an evil side
>Darkrai plays into his black mask design and also it's known for inducing never-ending nightmares, which is similar to the mental breakdowns
>Justice Arcana - Keldeo is part of the Swords of Justice
>Decidueye's design is based on Robin Hood
>Lokix - for obvious reasons
>Shiftry - This is a bit tricky, but Goro's Prince mask is similar to a tengu, which is the theme of Shiftry's design

I was about to add Zoroak but went with Lokix instead.
