GUYS IT WORKS BEAUTIFULLY, CHECK IT OUT:
-4 Ghost-types (i.e. Chandelure)
Okay, so the strategy is lead with Delcatty and Audino (both holding Focus Sashes). Audino uses Skill Swap on Delcatty to gain Normalize, Delcatty uses Fake Out/Protect to stall. Delcatty switches out to a waiting Ghost-type, such as Chandelure. Audino proceeds to use Entrainment on the opponents, giving them the Normalize ability. As all their moves are now Normal-type, nothing would touch Chandelure, and it could sweep without worry. Now this strategy would be PRIME if Chandelure had it's BW hidden ability, Shadow Tag, but alas, it does not in X/Y. You could even switch out to Wobbuffett or Gothitelle to utilize S-Tag. Would it still be a good strategy, or would it be too much work?
