I've been messing around trying to put together a mono fighting team, and this is what I came up with. It's only been average so far, so any constructive criticism would be appreciated! Here's a look at my team:
Infernape @Focus Sash
Nature: Hasty
Ability: Iron Fist
252 Att, 252 Spe, 4 SpD
-Thunder Punch
-Overheat
-U-Turn
-Stealth Rock
This guy is a mixed lead, with sash to get a Stealth Rock up, or it can U-Turn out in a bad matchup.
Chesnaught @Leftovers
Nature: Impish
Ability: Bulletproof
252 HP, 252 Def, 4 Att
-Stone Edge
-Seed Bomb
-Spiky Shield
-Leech Seed
Chesnaught is here to live a while, take an incoming Psyshock and kill Gengar with Stone Edge. Originally Hammer Arm was there but Stone Edge seemed to be the better option.
Machamp @Assault Vest
Nature: Adamant
Ability: No Guard
200 HP, 252 Att, 56 Spe
-Dynamic Punch
-Stone Edge
-Ice Punch
-Knock Off
Machamp is a tank. With the Assault Vest makes him hard to kill and No Guard Dynamic Punch can wreck walls.
Conkeldurr @Assault Vest
Nature: Careful
Ability: Iron Fist
252 HP, 252 Att, 4 SpD
-Thunder Punch
-Mach Punch
-Drain Punch
-Stone Edge
Conkeldurr carries out a similar role, if not identical to Machamp. Drain Punch for recovery, Mach Punch for Greninja and Thunder Punch for flying coverage.
Keldeo @Life Orb
Nature: Timid
Ability: Justified
252 SpA, 252 Spe, 4 HP
-Hp Ice
-Scald
-Toxic
-Secret Sword
I wasn't too sure on the moveset here, but Keldeo was here for special moves so any improvements would be welcomed.
Lucario @Life Orb
Nature: Timid
Ability: Steadfast
252 SpA, 252 Spe, 4 SpD
-Nasty Plot
-Aura Sphere
-Flash Cannon
-Dark Pulse
Lucario again is something I'm unsure of, with special moves and coverage to fairy and psychic types.
So there's the team. Please leave any comments or improvements; if anyone could incorporate a mega or spinner in there, that would be taken gratefully too.
