Ok heres part 2 of my rate.
Jokes aside though this is actually a very nice team with good synergy though a very unbalanced offence.
We have 2 physical moves out of a possible 24.
This means this team is litterally gona get sat on by Blissey.
Okay Shadow Ball is doing didly squat so that will be replaced.
Screw it lets cut to the chase just use this below set for complete devastation.
Trait: Snow Warning
EVs: 252 Atk / 4 SAtk / 252 Speed
This set outspeeds all base 100 Pokemon, as well as all opposing weather starters, with moves to counter them.
Though it should be noted E-quake is a 2HKO on Tyranitar.
Ok I know absolute nothing about this Pokemon :D but I know its not enjoying its dual stabs.
I guess you could try out calm mind and HP-Fire
Yeh but sorry on Keldeo not even smogon have a very good analysis for it.
Okay once again just use this set
Trait: Flash Fire
EVs: 248 HP / 252 SDef / 8 Speed
-Wil o Wisp
Gives your team what it needs (rocks)
This set is increadibly annoying to face and the special Bulk alows it to take many water hits and the fact it cant be hit by ground attacks is fun to abuse.
Sorry about this but just try this standard set.
Trait: Magic Guard
EVs: 252 HP / 252 Def / 4 SAtk
Set up is easy with the spread, not much else to say it works brilliant.
If your using an offencive variant I advice you push for using Mamoswine as it adds more phsyical offence as well as another Ice Shard abuser which is great currenty in Ou
@Choice Band/Life Orb/Choice Scarf
Trait: Snow Cloak
EVs: 4 HP / 252 Atk / 252 Speed
As much as I love Regice he has to go here the synergy has been corrupted by the previous replacment which is needed to actually help the team.
Trait: Iron Barbs
EVs: 252 Hp / 252DeforSdef / 4 Atk
Depends on evs Carefull or Impish
Regice is a brilliant T-waver and Ferrothorn does this same role as well as laughs at the fight weakness as it takes neutral damage then iron Barbs.
