Ok this is a gimmick set for Masquerain but it really does turn the tide of the match to my favor. It's quite difficult to pull off but its quite rewarding when it does.. I've had number of success with this set.
Masquerain [Bold] @ Rocky Helmet
[31/0/31/0/31/31] [HP:252, Def:252, SP Def:4]
Ability: Intimidate
Move Set:
Power Split
Sticky Web
Roost
U-turn
So basically this is my version of "suicide lead sticky web setter". Although it is not really a Pokemon suited for a lead position, so I advise to send it in the middle of battle or whenever there's a chance. It does a pretty good job against Physical Attackers and Slow Poke Walls. So pretty much send it against Pokemon such as Lucario, Mawile, Absol, Scizor, Kangashan, Aegilash, Chansey, Blissey even Keldeo etc. to do its job. Best bet that its able set up a Sticky Web against them before you die. There are instances I also toy with Physical attackers as Power Split is quite a fun gimmcky move. You could screw up your opponent's base Attack power that could force them to switch out.
I've had quite amazing instances using this fella as with most slow Physical Attackers such as Mega Mawile, Mega Absol, Mega Kangaskan that depended on Sucker Punch to strike first you could set up Sticky Web then proceed to Power Split thereafter even if they choose to use a different move Masquerain will still survived, sometimes it could manage to U-turn back to scout. Same goes to Mega Scizor, Shadow Sneak Aegilash, Breloom. Rocky Helmet is a useful item for it to get additional damage to these Physical attackers.
However keep in mind though that even with invested defenses and intimidate, Masquerain shouldn't be send out against Pokemon that knows any rock move. Masquerain could also be just a burden and deadweight if the match isn't in your favor. But once it does it job its quite rewarding. Still it could've been a better support Pokemon if it weren't for that abysmal 60 base Speed. It could've been a contender if it reaches the bench mark of 80-90 but either way it is a decent Sticky Web user with its plethora of support move. For teammate, it will do great if its supported by a screener or a cleric (paralyzer), trick room oriented, or speed booster supporter (tailwind).
Blah.. I might blurted out a nonsense set, however Masquerain with its useful ability, passable defenses and amazing support moves could hold its ground against top physical threats and set up sticky web or force a switch out. It may not be ideal for a OU spot but this gimmick its quite amusing to be witnessed. It walls like a pro!
Though if anyone could have a better EV Spread for it it would very much be appreciated to know.
