So I wanted to build a team around dragonite. I used the DD set with a few touches
(Jolly) 252 Attk/252 Spe @Life Orb
DD
Dragon Claw
Fire Punch
Roost
I prefer accuracy over power, especially with Dragonite's power. DC for stab and OHKOs. Thunder Punch for hitting things like steel, basic neutral coverage. Roost to keep the longevity up.
Next I need a lead. So I Picked an SR lead. Normally It would be fast so I picked Dugtrio
(Jolly) Dugtrio : Arena Trap
252 Attk/252 Spe @Focus Sash
Stealth Rock
Earthquake
Rock Slide
Toxic
SR to start some entry hazards. EQ for stabby attks, rock slide for neutral dmg and flinching. Toxic for a parting gift if I have doubts the poke will interfere with the rest of my team
Then I need a counter to things that might give Dragonite some trouble. IE Tyranitar, Mamoswine, Cloyster. So I got Infernape
(Naive) Infernape : Blaze
252 attk/ 252 spe @ Expert Belt
Flare Blitz
Close Combat
Vaccum Wave
U-turn
Flare Blitz for hefty sweeps against pokes like Metagross. Close combat for some more stab. Vaccum Wave is to counter Shell Break Cloyster, and to pick off pokes. U-turn to scout
Next, I need counters to dragons that are the same caliber as dragonite IE Garchomp, Salamence. I figured Weavile should do the job
Weavile : Pressure
(Jolly) 252 Attk / 252 Spe @ Life Orb
Ice Shard
Night Slash
Aerial Ace
Brick Break
Ice Shard for easy dragon kills, and to pick off pokes. Night slash for crits and stab against things like Jellicent, Gengar, Reuniclus ect. Aerial Ace for mere fighting types including the ever so popular Conceldurr. Easy kill for heracross as well. Brick Break for occassional Blissey and Ferothorns.
Next I needed something to patch ground and fire weaknesses. Here comes my Blastoise
Blastoise : Torrent
(Calm) 200 HP/ 52 Spattk/ 252 SpD @Leftovers
Rapid Spin
Mirror Coat
Scald
Dragon Tail
Definitely not a normal Blastoise. This blastoise is meant to be more of a special wall. Rapid Spin for SR and spikes. Mirror Coat goes well with blastoise. After playing a bit PO, I noticed almost no electric type pokes were able to OHKO me. So Mirror Coat away for the easy kill, although it does come with a revenge kill / easy kill later in the game. Scald for stab and burn, oddly enough does decent damage. Dragon Tail for roaring pokes away.
Lastly I needed something that could resist Toxic, take great hits, provide Spikes and SR in case they were blown away and Dugtrio died, and completely counter Excadrill and Conceldurr.
Skarmory : Sturdy
(Impish) 252 Defense/ 252 HP @leftovers
SR
Spikes
Brave Bird
Roost
Built In Sash? Awesome. Brave Bird for some decent damge and Roost for recovery
And that is my team. I AM a beginner, so advice and possible replacements would be great. I love feedback.
