Aerodactyl-Mega @ Aerodactylite
Ability: Unnerve
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Stone Edge
- Aerial Ace
- Earthquake
- Hone Claws
Mega Aerodactyl is the central focus of this team. I really like him and he's a lot of fun to play. Thanks to his extremely high speed, once a few counters are eliminated he can take care of the entire team after just one use of hone claws. Together, stone edge, aerial ace, and earthquake provide pretty good coverage.

Magnezone @ Choice Specs
Ability: Magnet Pull
EVs: 172 HP / 252 SpA / 84 Spe
Modest Nature
- Hidden Power [Fire]
- Flash Cannon
- Volt Switch
- Thunderbolt
Magnezone is a partner to Aerodactyl. It traps many of Aerodactyl's steel type counters, especially Scizor and Ferrothorn. In addition, it can checks water type counters. Flash cannon allows Magnezone to check fairy and rock types, particularly Mega Diancie. Because of Magnezone's high special attack and the choice specs, even neutral coverage on flash cannon or thunderbolt helps wear the other team down.

Gliscor @ Toxic Orb
Ability: Poison Heal
EVs: 244 HP / 8 Def / 200 SpD / 56 Spe
Careful Nature
- Taunt
- Toxic
- Roost
- Earthquake
Gliscor works well as a defensive pokemon, since he's immune to both electric and ground. He's a good switch from both Mega Aerodactyl and Magnezone. He can also stall out many physically offensive pokemon like Landorus, useful if my checks to those pokemon are already fainted. He also can stop many walls with taunt.

Heatran @ Choice Scarf
Ability: Flash Fire
EVs: 28 HP / 252 SpA / 228 Spe
Timid Nature
- Earth Power
- Fire Blast
- Flash Cannon
- Stone Edge
Heatran is another good switch from Magnezone, since he absorbs any fire hits easily. He's also a really good check to most fairy types. Fire Blast provides another check to the steel types which harm Aerodactyl, and he can often finish off a team with fire blast once his counters are gone. Earth Power makes up for what Fire Blast and Flash Cannon don't cover, and also takes care of other Heatran. Stone Edge can stop a Charizard or Talonflame on switch in.

Clefable @ Leftovers
Ability: Magic Guard
EVs: 252 HP / 172 Def / 84 SpD
Calm Nature
- Calm Mind
- Moonblast
- Soft-Boiled
- Flamethrower
Originally I had Sylveon here but Clefable's physical bulk and recovery through Soft-Boiled is really helpful. Clefable can check pokemon like Sableye and dragon types with moonblast, and can use flamethrower to stop counters, especially Ferrothorn. If Clefable's counters are gone, calm mind can offer another victory path aside from a Mega Aerodactyl sweep.

Keldeo @ Choice Scarf
Ability: Justified
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Scald
- Secret Sword
- Icy Wind
- Hidden Power [Bug]
I added Keldeo when I was having trouble with fire pokemon. Scald and Secret Sword provide really good coverage, Icy Wind can take down dragon types (and is also useful in lowering the speed of pokemon like Mega Manectric, so that Aerodactyl can finish them) and Hidden Power Bug is pretty much entirely for Starmie and Slowbro, who are a lot of trouble for my team if Magnezone is gone.
I still face some problems with Mega Sableye, Gyarados, Excadrill, and bulky water types (particularly Slowbro and Rotom-W). Thanks in advance!
