Need a good 3rd pokemon

[edmek55555]

Looking for a good pokemon for my 3v3 team. Preferably a good revenge killer or a good mixed wall with some offensive capabilities. Right now I am running

Ferrothorn: leech seed, toxic, protect, iron head
Item: sitrus berry.
Evs: hp 252, def 100, spec def 152
Nature: impish

Milotic: scald, dragon tail, rest, sleep talk
Item: Leftovers
Evs: hp 252, def 152, spec def 1oo
Nature: calm

I'd recommend a strong Fire-type to complete the Fire/Water/Grass core for nice coverage and synergy. If this team is for Battle Spot Singles, Mega Blaziken, Mega Charizard, or Talonflame would be great picks for the last slot. Arcanine, Heatran, or Chandelure are also options to cover Ferrothorn's quad fire weakness through Flash Fire.

I've thought about several of these. Blaziken simply doesn't hit hard enough without a swords dance to be a solid revenge killer and he easily gets one hit koed. I have thought about mega charizard, volcarona, or Talonflame. But my biggest threats are pokemon that can't be one hit koed but can one hit ko my pokemon, like swords dance ferrothorn and escavalier. Even when I used arcanine his flamethrower wasn't a ohko

It depends on how you and your opponent trained your Pokemon. Timid fully invested Arcanine's Flamethrower always gets the OHKO on 252 HP/252 Sp. Def Ferrothron and Escavalier without assault vest (which wouldn't be possible since you said they had swords dance. What Pokemon have been giving your team problems?

Also, if you really want a bulky fire type but can't get Heatran and Entei on your team, Mega Charizard X and Rotom-Heat can actually work well with bulky sets.

Additionally, I would recommend changing Milotic's moveset to something more offensive like: Scald/Hydro Pump, Ice Beam, Recover/Mirror Coat, Icy Wind/Dragon Tail with possibly an assault vest and Modest nature. In 3v3 you need to make sure all 3 of your Pokemon can at least put on some offensive pressure of some kind or really cripple with some status move(s). Stall doesn't work too well in 3v3 singles. I would also give Ferrothorn a Brave nature and replace Iron Head with Gyro Ball, as well as Toxic for Seed Bomb.

Give any of those a shot and see if it helps your matchup more, then come back and see if your team still needs something more to deal with particular threats to your team.
