What are good evs+nature for this particular Blastoise?

Question

Ice Beam(covers most common weakness)
Surf(STAB)
Iron Defense(power up lower defensive stat)
Toxic(STALL)

This is a wall it will have Rain Dish, leftovers, and Rain support. I was think most evs in hp and S.def and a little in S.atk. Suggest moves if you think of better ones(to those who don't know Hydro Pump and Blizzard are not good idea's)

Comments

Probably defense, and sp.attack, plus maybe some hp too.

Answer 1

I would say..

Blastoise (M) @ Leftovers
Trait: Rain Dish
EVs: 160 HP / 96 SAtk / 252 SDef
Calm Nature (+SDef, -Atk)
- Surf
- Ice Beam
- Toxic
- Iron Defense

Now for the moveset, I like it, but you could try this.

Blastoise (M) @ Leftovers
Trait: Rain Dish
EVs: 252 HP / 136 Def / 120 SAtk
Calm Nature (+SDef, -Atk)
- Surf
- Ice Beam
- Toxic or Protect
- Aqua Ring

This is just pretty much having so much Hp restoration its not funny, although I would go with your set, this is always an alternative.

Hope I Helped :D
