Could I please have a list of good mixed walls that and use Spikes/Stealth Rock that can use an attack like Whirlwind.[if there are any]

[Rick52]

So... you want:

-Mixed Wall
-can use Spikes/Stealth Rock
-can use Whirlwind, possibly Roar

Bastiodon can Roar, set up Stealth Rock, and is a mixed wall. However, it has 4x weakness to Ground and Fighting, so... be careful of that.

Next best fits for your requirements:
Skarmory (Spikes or SR, Whirlwind/Roar, but only Physical wall)
Suicune (mixed wall, can Roar, but no Spikes/SR)
Swampert (Roar, Spikes/SR, but is more bulky than wall (albeit mixed))
Hippowdon (like Skarmory, but less Def for more SDef (not mixed though))

Ok thanks Rick.

I have personally used a Swampert like that with great success. This is its moveset:

Swampert@Leftovers
-Impish-
Avalanche
Waterfall
Stealth Rock
Roar

Only bad part about Swampert is its 4x weakness to grass.

[Pencil Thief]

Correct.

In the case that a grass pokémon shows up, use Avalanche. They should attack first, so just hope that you survive. If you survive, Avalanche's effect coupled with Ice's super-effectiveness on Grass types should take the grass pokémon down.

Can Swampert serve as a mixed wall?

[Chris!]

It can take a few hits from both sides. "mixed walls" unfortunately are inferior to their non-mixed counterparts, but a bulky tank sweeper type like Swampert should work well.

Oh, I'm sorry, I forgot to post the EVs for that Swampert. They would look something like this: 252 HP, 116 attack, 116 Defense, 26 Special Defense

Ok. Thanks guys.
