Ideas, judgement, whatever on teams based on themes

a circus/carnie/fair team

conkeldurr is obvious
drifblim is a circus balloon
grumpig is for pig races (i dunno how widespread that is but it seems like a circusy pokemon)
magmortar is a fire-breather
liepard's pattern seems appropriate to me and also prankster fits
ambipom is a circus monkey plus its got thief
