Primal-Groudon and Exeggutor VGC16?

[Corn]

This actually sounds very interesting, I've also been fooling around trying to find counters to OP pokes like P Groudon and Power Gem Xerneas, I did not think of a skill swap set up though that's a awesome sounding strategy and may be something I need to consider, I've been using my Mega Rayquaza to counter the Primals and it works pretty good, but if a skill swap comes into play that could be a problem.

Thanks for sharing.
