While I do like Burgh with his artistic self, I'm gonna be voting for the triplets on this one, hehe~ Definitely like their designs more~
The level advantage is going to turn things in Burgh's favour automatically. Chili would have the best chance against him but would have trouble with Dwebble, Cress would have the advantage against said Dwebble, and... poor Cilan wouldn't have an advantage at all.
And Pansear. Fire is one of my two favourite types, so Pansear would have an advantage over the other two in the favourites department XD
