Yeah, I don't know either but I know Sableye isn't countered by Espeon though due to Foul Play.
I think Heatran is probably the best counter for it.
Both Sableye and Espy are antithesis of each other when it comes to their approach to status-fodder. They're both great pokes. Both are on my team that I have been tweaking. --- **** you SE for trolling us with that TWEWY port. I hate you.
