Torterra
Since Torterra is your lead, I suggest giving it Stealth Rock. Your Team will benefit from it and your opponent will be wary to switch in an Ice Type against Torterra. You want a lead Torterra to be Bulky, so replace Swords Dance with Curse because you get a Defense Boost as well as a Attack boost. Since your Torterra has an Adamant Nature, you might want to replace Giga Drain(special) to either Wood Hammer or Seed Bomb for that extra power. Make your EV spread 252 Defense, 168 HP, 84 Attack for that extra Bulk.
Blaziken
Okay, this Blaziken is not taking advantage of its ability, so I suggest:
Blaziken@ Life Orb
Trait:Speed Boost
Adamant Nature
EVs:252 Speed, 252 Attack, 4 HP
- Protect
- Swords Dance/ThunderPunch
- Hi Jump Kick
- Flare Blitz
Okay, that should be a more effective set. Protect allows you to get a free Speed Boost up. Swords Dance raises your Attack to blistering levels and ThunderPunch is coverage against. Water types. The other 2 are STAB. This is a better set that takes advantage. Of its new ability. I hope you use it.
Blastoise
I believe. This is a Special Wall? Well I recommend you change the Nature to Calm Nature and use this moveset:
- Toxic
- Scald
- Protect
- Ice Beam/Rest
A Special Wall. It Walls as it Stalls! This is the basic Staller set that needs no explaining. You can always replace Blastoise with Empoleon for a Wall because of its Steel typing.
Sceptile
Its pretty good honestly. Since it is a Sweeper, you want to outspeed. So, give it a Jolly Nature. Your Moveset can also use a little adjustment. As SF said above, you need Swords Dance to cause some damage. Replace Earthquake with Swords Dance. With the move Acrobatics, you get a boost from Flying Gem when you use it, so replace Night Slash with Acrobatics, because Night Slash only covers 2 types. Also replace Grass Gem with Flying Gem.
With the other two, SF suggested what I would have, so because I don't want to copy him go with what he said.
