RM Lead Swampert

This is basically a different version of the regular lead Swampert.

Swampert @Leftovers
Relaxed
252HP / 128Def / 128Atk
-Stealth Rock
-Waterfall
-Brick Break
-Roar

Well, as you can see, I've added Waterfall and Brick Break. I've also changed the EVs for more power. Brick Break is for the dual screeners and some steel walls. Waterfall is for STAB and coverage and so I don't get walled by ghosts. Stealth Rock is standard and Roar is just...Roar.

What do you guys think?

yea its a good variation of the standard lead

Looks like a good set, I can't see anything wrong with it or to comment on. It'll work fine, I think. With some bulkiness to survive even later into the game it'll be a worthy addition

Screens arent super common, so maybe the 100 power hammer arm instead?

Unless you REALLY want to break the reflect set up by azelf every once in a while

This isn't bad. Although I also believe that dual screeners aren't too cmoon, but if you're weak to HO then it's good to have someone to handle the azelf, bronzong, etc. screeners. The only suggestion I can make it to make the ev's 236 HP so you can hit 400 HP, a lefties point. The rest can be poured into defense.
