@Afro-G I'm in the UK, so my Regionals aren't soon (as far as I know). Anyway, I'm experimenting a bit at the moment: I did have a Gengar variety along with Flygon X, but now I'm focusing on a Nidoking TR/ Nidoqueen RR deck (they work well together but it's a long setup when you only have one BTS).
