Ahem. My team would consist of my starter: Treecko that would eventually evolve into Sceptile

A Hydreigon

An Eevee who I'd evolve into Espeon.

A Houndour/Houndoom

Then we have a Lycanroc, midnight form because that's the coolest one *smirks*

And last, but not least at all. We have Kecleon because he's really awesome.

And there's my team of 6.

Treecko, Hydreigon, Espeon, Houndoom, Lycanroc midnight form, and Kecleon.
