The synergy of the team is amazing - I've yet to see a threat where I've thought 'fuck, there's nothing that can take this...'. It also keeps momentum really well which is quite important - I tend to play a high-tempo game and it just suits me. ._.
I'm actually familiar with CobaLatias already, in a sense - in DPP, I ran an offensive core of Lucario/Latios (diff pokes, same types).
