I'm planning to try out Zygarde on Wifi, but I want to exploit what makes Zygarde unique rather than just using it for the sake of using it (i.e. I'd run Garchomp if I wanted an offensive sweeper).
I planned something like a Careful Zygarde @ Leftovers, with at least 31/xx/31/xx/31/xx (I actually already caught one like this! Though I can catch another), EV's 252 HP / 252 SpD / 4 Def. Since he gets an excellent 100% accurate Glare, I was going to try to make him a bulky parashuffler, who (unlike Dragonite) has a 100% paralyze even against enemy Ground types. Thus two core moves are Glare and Dragon Tail, to spread paralysis around the enemy team (though I admit on Wifi sleep is a better status, but roll with it). I'm not sure exactly what else to run. I should probably run Earthquake to KO any electric types that might try to absorb the Glare paralysis (not that electric types are a good switch-in to Zygarde anyway) and to have a generally strong STAB. Since Zygarde is so bulky I had Coil recommended to me as a 4th move, so that he can set up to deal more damage in a pinch and also guarantee Dragon Tail hits.
One problem is that this set does exactly nothing to Togekiss aside from paralyzing it, and it isn't too useful against anyone immune to Earthquake in general. I also had Stone Edge recommended as a possibility, but I'm a little leery since that would mean dropping Coil, which has obvious synergy with Stone Edge. Unboosted 80% accuracy is alright, but I prefer to keep riskier moves on my glass cannon sweepers rather than my walls... a risky move on a sweeper probably only needs to land once to get a kill. Not to mention the additional irritation of losing to bad luck in Wifi, since it's not like you get the benefit of hearing "gg I would've lost that game 4 times out of 5" from your opponent afterward.
In short: should I suck it up and take Stone Edge over Coil? Should I run Coil and just switch out on Pokémon like Togekiss? Are ice users like Mamoswine and fairies (who can't be shuffled) going to ruin my day before I spread too much paralysis?
Should I just run M-Venusaur like every other trendster and put all 6 enemy Pokémon to sleep? >.>
edit: let me know if this belongs in Casual XY SQSA. On the one hand this question is technically tailored toward the Wifi metagame, but on the other hand the Battle Spot board does NOT have SQSA yet, and Casual XY SQSA seems to be more for gameplay questions rather than the battling metagame.
