I don't really mess around with the lower tiers such as NU or PU, but I decided that I wanted to give it a try, and I believe I came up with a very good team here. Of course, tweaks and improvements can be made, so feedback is appreciated.
Lake Placid (Feraligatr) (M) @ Life Orb
Ability: Torrent
Shiny: Yes
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Dragon Dance
- Waterfall
- Earthquake
- Ice Punch
Feraligatr is the main threat of the team, reaching very dangerous speed and power thanks to its access to Dragon Dance. Waterfall is the STAB move of choice here, doing a lot of damage to anything that isn't resisted, especially after a D-Dance is set up. Earthquake provides decent coverage against Steel types, and any Rock types that are packing the Rocky Helmet. Ice Punch provides coverage against Ground and Flying types, hitting decently hard once a D-Dance set up. Adamant Nature has been chosen over Jolly since I'll be increasing Gatr's speed anyway. Life Orb provides an extra kick to all of its attacks, making Feraligatr a serious threat to be reckoned with.
Autumn (Leafeon) (F) @ Leftovers
Ability: Chlorophyll
Shiny: Yes
EVs: 252 HP / 4 Atk / 252 Def
Impish Nature
- Leaf Blade
- X-Scissor
- Heal Bell
- Toxic
Feraligatr has two massive threats in Electric and Grass types, and ironically enough, the best type that resists both of these is also Grass type. After looking around for Grass types to be a partner for Gatr, Leafeon was chosen as a Physically Defensive Cleric. The EV spread makes Leafeon a surprisingly powerful defensive juggernaut. Leaf Blade is great at hitting Rock, Ground and Water types, while also providing STAB. X-Scissor completely destroys threats like Malamar, and other Dark and Psychic types. Heal Bell makes Leafeon a powerful Cleric, getting rid of any statuses that other walls try to put onto Lefeon. Finally, Toxic provides ways of getting residual damage onto other Pokemon, and helps to take out opposing walls.
Nala (Pyroar) (F) @ Life Orb
Ability: Unnerve
Shiny: Yes
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Hyper Voice
- Fire Blast
- Dark Pulse
- Hidden Power [Grass]
Pyroar is a powerful Special Sweeper that, when paired with a Life Orb, becomes a huge threat. Hyper Voice and Fire Blast are two very powerful STAB moves that creates a very unique STAB combination. Dark Pulse provides coverage against Ghost types, which can't even touch Pyroar with their STAB. Hidden Power Grass is an incredibly powerful coverage move against threats like Seismitoad, and other Ground and Water types.
Mystic (Uxie) @ Leftovers
Ability: Levitate
EVs: 252 HP / 4 Atk / 252 SpD
Sassy Nature
- Stealth Rock
- Knock Off
- Thunder Wave
- Zen Headbutt
Uxie provides my team with a Specially Defensive Support Pokemon that is capable of setting up Stealth Rocks for residual damage, as well as set up Thunder Waves to cripple fast threats like Sneasel. Knock Off is useful to get rid of Eviolites and Leftovers, hindering many walls in the tier. Zen Headbutt is STAB, providing some coverage against Fighting Type threats. Not really much else to say about this set here to be honest.
Salem (Mismagius) (F) @ Choice Scarf
Ability: Levitate
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Shadow Ball
- Dazzling Gleam
- Destiny Bond
- Energy Ball
Mismagius is very versatile as a Pokemon. Running Nasty Plot, Specs, and even a powerful Choice Scarfer. Mismagius can out speed so many threats and hit hard with its naturally high Special Attack. Shadow Ball is the STAB of choice, hitting Ghost and Psychic types hard. Dazzling Gleam provides coverage against Dragon, Dark, and Fighting types. Energy Ball hits Ground and Water types, while lastly, Destiny Bond. This is a last resort move for when Mismagius is almost dead, or for a threat I know I can't take down.
Christmas (Cryogonal) @ Assault Vest
Ability: Levitate
Shiny: Yes
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Rapid Spin
- Freeze-Dry
- Hidden Power [Fire]
- Signal Beam
I believe this is a unique Cryogonal set. Most Cryogonal are, I've found, Specially defensive Rapid Spinners that provide support. However, this is an offensive spinning set with Assault Vest, making its already impressive Special Defensive even more powerful. Freeze-Dry is an amazing move for Ice types to have, hitting Water types as well as all the other types Ice normally hits. Hidden Power Fire allows Cryogonal to hit opposing Ice types, and Signal Beam is honestly just a filler move, as I really don't have any other moves that really fit.
