If you like keckleon I know it can become a good special wall but gets outclassed by other OU special walls like so.defensive arcanine.
Good pokemon I would recommenced: Metagross.
It's basically a super awesome pokemon. I've used it a lot. You can try 2 builds on it, Choice band and agility sweep better known as AgiliGROSS CB METAGROSS: EV's 252 attack, 252 speed/HP Adamant
Meteor mash,Thunder punch,Earth quake,Pursuit/Explosion.
You can run just 96 HP Eve to live a +1 DD Gyarados's Earth quake. (31 HP and at least 30 def IVs) AgiliGROSS: EV's 252 Attack 96speed throw 160 HP
Meteor Mash,Thunder Punch,Earthquake,Agility. Adamant. Leftovers/plum berry coz:4 SpA Metagross Psychic vs. 252 HP / 4 SpD Weezing: 132-156 (76.7 - 90.6%) -- guaranteed 2HKO
You can opt for brave nature with 252 attack HP with move set: Meteor mash,thunder punch,earthquake,psychic.(for wheezing a common physical deff and other physicals walls too)held item: Leftovers or lumy breey incase weezing burns you.
*You can try substitute which works great against Umbreon.
Sceptlie:
Sceptile too is another great psychical sweeper but you can make a special attacker and punish your opponents phsycal walls.
You can run SD set: 252Atk/Speed Jolly Leftovers/Lumberry
LeafBlade/Sd/Tpunch/Eq
Another set is turning sceptile into an Annoyer:
252 speed/sp.atk Timid Leftovers
Leech seed/Subsitute/Leaf blade/hp ice/fire
You can even run mixed ^
Last but not the least:
Gardevoir
It can be a wall OR a sweeper which confuses your opponent. Special Sweeper: 252 Sp.atk + Speed 4 HP Timid-Trace-Leftovers
Calm Mind-Psychic-Thunder Bolt-will o wisp
The idea is to set up on something like a jolteon, and stop physical sweepers with wow and sweep with psychic and tbolt.
Support/Wall: 252 Hp + SpDdef 4 def Calm Trace.
Moveset: WoW/Psychic/Wish/Protect OR Heal bell
Basically your blissey ripoff bit it with wow.
I can only recommend these, you can try more sets by yourself, we have PTS currently running, get a pal and spawn comps and try them out. Good luck with your future! And may the rng be ever in your favor. ;3
