Hey I finally started playing again since January and wanted to make an RMT with the first team I cracked 1600 with so I could get some advice to climb into the ladder!
This team is again another attack oriented team (didn't start out that way, wanted equal special attackers but just happened I have five of them now >.>) with some diversity in typing and strengths that allows the opportunity for one to setup and start a sweep while revenge killing along the way.
Talonflame
Ability: Gale Wings
Item: Sharp Beak
EV: 252 Atk, 19 HP, 237 Spd
Nature: Adamant
Moves:
Brave Bird
Flare Blitz
Roost
Swords Dance
A very standard Talonflame with the exception of the EV's which I wanted to try out to see if outspeeding Modest Thunderus-I would work out, I could stand to change that around. He's the first listed because he is still the most reliable sweeper/revenge killer in the game by far. Everyone likes to comment on how Aegislash is so technical and can make or break a team with good prediction but Talonflame in my opinion is the far more rewarding of the two for correct prediction. The only pokemon it really can't outsmart is Unaware Quagsire which is a pokemon too stupid to outsmart (literally). Only other thing to say is I'm contemplating getting rid of Flare Blitz for something like U-turn or even will-o-wisp because I'm unsure of how many things I actually try to Flare Blitz.
Mega Blastoise
Ability: Rain Dish > Mega Launcher
Item: Blastoisinite
EV: 252 HP, 252 SpA, 4 SpD
Nature: Modest
Moves:
Rapid Spin
Scald
Dark Pulse
Aura Sphere
Mega Blastoise is the best rapid spinner. Everyone says it but I didn't really believe it until I tried out all of the others to try and get a more powerful mega in there. But nope none are as consistent as him and to be honest he's still a freaking powerhouse. Like damn I was worried about not having enough special after I saw how my team panned out but he provides a ton of special attack and coverage. I decided to order the list of pokemon in terms of importance to the team and I didn't know how much I valued him until I started to think about the team as a whole. He saves everyone on the team and really patches up the flaws.
Cloyster
Ability: Skill Link
Item: Focus Sash
EV: 252 Atk, 252 Spe, 4 HP
Nature: Adamant
Moves:
Ice Shard
Icicle Spear
Rock Blast
Shell Smash
I was surprised to look at the Smogon OU Viability Ranking Thread and see Cloyster as a D lister. He's still just about the highest potential self-reliant sweeper in the game. What I mean by that is if you can eliminate his threats, you win the game automatically with him up at full HP without hax. Okay that sounds like something you can say about most sweepers but with Cloyster it's easily identifiable what his threats are and your win conditions. Keep status off him, keep stealth rocks off the field, break some walls he can't handle, and let the beast out. This guys won me plenty of games where it's 1v4 and the rest of my team has done their job dealing with the walls.
Landorus-Therian
Ability: Intimidate
Item: Assault Vest
EV: 252 Atk, 252 HP, 4 SpD
Nature: Adamant
Moves:
Knock Off
Earthquake
U-turn
Rock Slide
Probably the most unconventional build I'm running but it's pretty funny how well it holds up. Landorus-T ends up being a wall for both types of damage and a solid damage threat as well. He's almost always my lead just to get momentum up and trick out their lead. You would be surprised how many deoxyses (deoxysi?) def or spe will try and taunt for stealth rocks and get smacked with knock off, guarenteeing 2HKO on def and OHKO spe even with focus sash. Or the countless times a special sweeper is brought in to use hidden power ice on him only to be OHKO'd. I brought him in mainly because I wanted a ground to take electric type moves like thunder wave or volt switch which screw up the majority of my team. Most other grounds are not as useful or as threatening besides Hippowdon and he screws up a lot of the team with Sand Stream.
Bisharp
Ability: Defiant
Item: Life Orb
EV: 252 Atk, 252 Spe, 4 HP
Nature: Jolly
Moves:
Knock Off
Sucker Punch
Iron Head
Swords Dance
Again Bisharp like Landorus-T was mainly brought in for typing reasons to ignore certain types of stall and create diversity, namely to take on toxic. Very useful at revenge killing but hardly ever gets the setup he needs to sweep as his speed is good but not great and sucker punch can be out-predicted. He just gets the job done really, not much to say he covers what the others don't.
Breloom
Ability: Technician
Item: Life Orb
EV: 252 Atk, 252 Spe, 4 HP
Nature: Jolly
Moves:
Mach Punch
Bullet Seed
Spore
Swords Dance
Breloom is like the other bottom two mainly a type coverage guy. No more Spore or Sleep Powder, gets rid of bulky Water types, sets up Sleep Clause, and gives fighting type coverage. I used to run with a Scrafty and wanted to maintain his strengths in my team so he kinda was split into Breloom and Bisharp who each keep his coverage while their additional types add more utility and extra coverage. He like Bisharp doesn't get to set up that often but I feel there are more scenarios that can happen with him setting up than Bisharp simply because of Spore, albeit it is a bit of a risk due to the fickle nature of Sleep. Also if you haven't noticed 4 out of 6 of my pokemon keep priority moves which is ridiculously useful to keep on revenge killing until one can do a setup sweep.
Acknowledged Problems: Lack of Taunt or setup counter. Basically this means I have to make sure I have a proper way to kill off baton passers or use my very limited status affliction.
(I will add other problems to the list that are brought up and check them off if they have been solved.)
I don't really have the patience to create an entire threat list but I can say for now Bulky Waters are pretty hard especially Unaware Quagsire and Extremespeed users.
