Weavile > Should never be used to S.Atk / too weak in S.Atk and no time to set up Nasty Plot (with your Pokemon; with some Sleep status, you may or may not be able to get 1 Nasty Plot in, but Weavile would do more damage using unboosted Physical attacks or Swords Dance)
Togekiss > Moveset is bad. Needs some Roost or Nasty Plot and a paralyzing move like Thunder Wave or Body Slam. Ability should be Serene Grace.
Infernape > Your stats are a mess. Its Atk and S.Atk should always have one distinctly higher than the other. Use only Physical attacks or only Special attacks. Another option is Mixape with Grass Knot / Flamethrower / Nasty Plot / Close Combat.
Espeon > This Espeon is pretty bad.
Electivire > Needs more Earthquake, Ice Punch, and Cross Chop.
Froslass > She's pretty bad without Hail. Too many Physical moves; it prefers Shadow Ball / Thunderbolt / Blizzard / etc. She does a good job setting up Spikes too and is fast enough to Taunt or Destiny Bond.
Mamoswine > Needs more Ice Shards / Ice Fangs, Stone Edge and Superpower.
Vespiquen > This one sucks. She can tank well with Defend Order and Roost (Roost over Heal Order). Other than that, she is pretty bad. Also, it has too many weaknesses.
Tangrowth > Fairly bulky, but the set sucks. Cbf for this one.
There is a potential danger in using any combination of these Pokemon. For one thing, many of them share the same weaknesses.
FIRE - Weavile / Proslass / Mamoswine / Vespiquen / Tangrowth
ROCK - Weavile / Togekiss / Froslass / Mamoswine / Vespiquen
GROUND - Weavile / Infernape / Electivire / Mamoswine
FLYING - Infernape / Vespiquen / Tangrowth
Almost any combination of your team will be OHKO'd by a Pokemon with Stone Edge / Earthquake. The high possibility of Crunch makes this combination even more fatal.
