If it's anything like NC, then lots of Yveltal and Donphan, and little to no VirGen and Seismitoad.
Also I want to correct this just so you don't get the wrong idea.

As an example, lets say I have 3 decks: Metal, VirGen, and Donphan
I go to a medium sized cities tournament and there's a lot of people playing Yveltal and VirGen. I can cross off VirGen off my list because it has OK matchups to yveltal and the mirror match up. I can also cross off Metal as it is subpar to yveltal and OK against VirGen. The 'play' for me seems to be donphan as it has a great match up to VirGen, and an OK yveltal matchup.
VG does not have a ok (it's a bad matchup) to Yveltal. Metal beats some Yveltal variants easily but not ones with Garb or hard charm. Metal destroys VG easily (and it beats Donphan). Donphan gets rekt by Yveltal.
