So... This is the team I fought Fritjof with. I lost, so please give me some help! I'll most likely use it in the future.
Honchkrow (M) @ Choice Scarf
Ability: Super Luck
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Drill Peck
- Night Slash
- Steel Wing
- Superpower
Drill Peck kills Fighting and Bug types that threaten the rest of my team. Night Slash is STAB that gets really good with Super Luck. Steel Wing covers Rock and Ice types, but this can be replaced for just about anything. Superpower also covers Rock and Ice types. This Honchkrow is supposed to be a physical sweeper.
Umbreon (M) @ Lum Berry
Ability: Synchronize
EVs: 252 HP / 128 Def / 128 SpD
Impish Nature
- Payback
- Toxic
- Wish
- Protect
Payback is STAB so Umbreon isn't Taunt bait. It usually gets the damage boost because of Umbreon's low Speed. Toxic, Wish, and Protect help Umbreon stall out opponents and keep itself healthy. This Umbreon is supposed to be a wall/staller.
Houndoom (M) @ Life Orb
Ability: Flash Fire
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
- Flamethrower
- Dark Pulse
- Sunny Day
- SolarBeam
Flamethrower is STAB that covers this team's Bug weakness. Dark Pulse is STAB. Sunny Day sets up one-turn SolarBeams, boosts Flamethrower, and makes Water types less effective. SolarBeam covers Rock, Ground, and Water types, all of which are super effective against Houndoom. This Houndoom is supposed to be a special sweeper.
Drapion (M) @ Leftovers
Ability: Sniper
EVs: 252 HP / 4 Atk / 252 Def
Jolly Nature
- Night Slash
- Cross Poison
- Aqua Tail
- Toxic Spikes
Night Slash and Cross Poison are STAB that both pair well with Sniper thanks to a higher critical hit ratio. Aqua Tail covers Drapion's only weakness in Ground. Toxic Spikes puts pressure on the opposing team and discourages frequent switches. This Drapion is supposed to be a physical tank.
Hydreigon (M) @ Choice Band
Ability: Levitate
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Crunch
- Outrage
- Rock Slide
- U-turn
Crunch and Outrage are STAB moves that do ridiculous damage with a Choice Band. Rock Slide covers Bug types and U-turn helps scout moves and retains momentum. This Hydreigon is supposed to overwhelm the opponent through sheer power.
Weavile (M) @ Flying Gem
Ability: Pressure
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Night Slash
- Ice Punch
- Low Sweep
- Aerial Ace
Night Slash is STAB and is nice with the boosted crit rate. Ice Punch nails common Ground types. Low Kick covers other Dark types that the rest of the team might have problems with. Aerial Ace covers Bug and Fighting types, and it gets a one-time boost thanks to the Flying Gem. This Weavile is supposed to kill Ground types, as this team doesn't have many answers to them.
I'd like to credit DarkTyphlosion for the Honchkrow moveset (for the most part). If you don't want me using it, then I'll change it DT. All help is appreciated!
