252 HP / 120 Def / 136 SpD

Keep using Ancientpower, hope to get the boost (20% chance with Serene Grace), beat the crap out of the Skarmory that comes to Roar / Whirlwind you. Pity Togetic can't get Thunderbolt or Thunder to deal with both Skarmory and Suicune. Togetic needs Fire Blast to 2HKO Skarmory, but if you absolutely hate missing, Flamethrower is still an option. You have a 33.6% chance to get one Ancientpower boost, 29.4% chance to get 2 boosts, a 14.7% chance to get 3 boosts, and a 5.52% chance to get 4 or more boosts, assuming you hit with all 8 PP.

2v2 Standard

Leftovers Serene Grace Calm
Moveset EVs
~ Follow Me
~ Counter
~ Softboiled / Light Screen / Reflect
~ Thunder Wave / Seismic Toss
252 HP / 160 Def / 96 SpD

This is a 2v2 set. Use this with a Pokémon with a way to set up and a good attack stat. People may use Rock Slide to hit both Pokémon, so Counter them back. Thunder Wave is a good support move, Softboiled for healing, but Togetic can't survive many attacks in 2v2.

Other Options

Charm helps against physical attackers, and Yawn can force switches.

It learns many support moves, figure something out yourself. Above sets are just random ideas that came to mind—You can pass Wishes, Mirror Move Spikes, etc.

EVs

Togetic has excellent Special Defense and nice Defense, so boost HP and one of those stats.

Opinion

Variable, surprising, overall usable even in OU teams.

Counters

Any STAB Rock attack can KO it, Togetic is also weak offensively. You can easily Substitute against it and boost your stats or just pound it with attacks. But watch out for Thunder Wave.
