Name: Magmortar
New Stats: 90 / 105 / 82 / 125 / 95 / 93
New Typing: Fire
New Abilities: Flash Fire, Mega Launcher
Movepool Additions: Aura Sphere, Dragon Pulse, Dark Pulse, Eruption
Justification: Mega Launcher was added due to Magmortar's arm cannons, Aura Sphere, Dragon Pulse, and Dark Pulse were added to take advantage of Mega Launcher,
and Eruption was added because Magmortar lives in volcanoes.
Niche in OU: An extremely versatile wallbreaker. Magmortar can run special sets with Specs and Mega Launcher, physical sets with a Band, and Belly Drum sets. It can also attempt to sweep with a Choice Scarf and Eruption, but it might be too slow for that.
Example Sets
Name: Torkoal
New Stats: 95 / 100 / 140 / 105 / 90 / 60
New Typing: Fire/Ground
New Abilities: White Smoke, Shell Armor, Dry Skin
Movepool Additions: Slack Off, Rock Polish, Ancient Power
Justification: Ancient Power and Shell Armor were added because Torkoal is a turtle, and they have incredibly long lifespans, and Slack Off provides reliable recovery
Niche in OU: Torkoal's niche hasn't changed, but it has become better at what it does. Increased speed and attacking stats allow Torkoal to run Shell Smash effectively, and reliable recovery allows it to safely pull off defensive sets.
Example Sets
Name: Pyroar
New Stats: 86 / 108 / 80 / 127 / 74 / 115
New Typing: Fire / Fighting
New Abilities: Pressure, Mold Breaker, Moxie
Movepool Additions: Focus Blast, Storm Throw, Slack Off, Flare Blitz
Justification: Focus Blast and Storm Throw allow Pyroar to take advantage of its new typing, Flare Blitz allows physical sets to have a powerful Fire-type move, Pressure is essentially a more viable version of Unnerve. Moxie and Slack Off were added as references to real-life lion behavior.
Niche in OU: Pyroar's movepool and improved stats make it difficult to predict what it's going to do. It could be running physical sets, special sets, mixed sets, or even support sets.
Example Sets
Name: Rapidash
New Stats: 90 / 120 / 85 / 90 / 90 / 125
New Typing: Fire / Fairy
New Abilities: Flash Fire, Unburden, Reckless
Movepool Additions: High Jump Kick, U-Turn, Work Up, Play Rough
Justification: Unicorns are usually associated with magic, so a Fairy typing was appropriate. Play Rough is the obligatory physical STAB move, High Jump Kick was added because horses have powerful kicks, and Unburden was added because horses can move incredibly fast. Reckless was added primarily for competitive reasons.
Niche in OU: Rapidash has enough recoil moves to be a powerful Reckless-based wallbreaker. It's also the fastest user of Unburden.
