Hi Shiny Serperior,
You don't really explain why this Pokémon and not another and that's the problem, I don't really find any strategy and it starts at the beginning. Your core isn't the best for a Double Dragon Team. Why ? Because their counters are differents. Let me explain you. Haxorus' counters are : Skarmory, Scizor, Ferrothorn and Forretress. Latias' counters are : Blissey, Ferrothorn, Chansey, Scizor, Tyranitar, etc etc etc. The problem on your Latias is the lack of
Hidden Power Fire. Thunderbolt is useless on Latias, HP Fire is much better. But forget Latias on this Team if you wanna play around Haxorus. Use a
Dragonite instead of Latias because both have the same counters. Something like that :
...
Dragonite (M) @ Lum Berry
Trait: Multiscale
EVs: 252 Atk / 252 Spe / 4 HP
Adamant Nature (+Atk, -SAtk)
- Dragon Dance
- Outrage
- Fire Punch
- ExtremSpeed
Skarmory, ScarfLandorus, ScarfTerrakion and Scizor are really annoying for this combo. Of course, the goal here is to kill them, but when you're setting up your Dragonite or your Haxorus, so you need something to switch on it. Keep
Forretress for that and in addition it can Rapid Spin for your Dragonite. But change its Set :
...
Forretress (M) @ Leftovers
Trait: Strudy
EVs: 252 HP / 180 Def / 76 SDef
Relaxed Nature (+Def, -Spe)
- Stealth Rock
- Spikes / Gyroball
- Rapid Spin
- Volt Switch
Now important thing, you need a
Weather Inducer and
Ninetailes is the better one there. The Sandstorm hurts Haxorus and Dragonite (breaks Multiscale) and the Rain isn't a good choice for
Fire Punch... So it's why the Sun is the better Weather for your Team. Use it instead of
Porygon2.
...
Ninetailes @ Leftovers
Trait : Drought
EVs : 88 HP / 252 SAtk / 168 Spd
Nature : Timid ( +Spd / -Atk)
- Fire Blast
- Will o Wisp
- Hidden power [Ice]
- Sunny day
Who says Sun says
Dugtrio. Dugtrio is important there for trapping
Politoed and
Tyranitar and winning the Weather War. You can even trapp Terrakion, Heatran etc. Use it instead of
Mienshao which is useless there.
...
Dugtrio (F) @ Focus Sash
Trait: Arena Trap
EVs: 252 Atk / 4 SAtk / 252 Spd
(Ivs for 201 HP)
Jolly Nature (+Spd, -SAtk)
- Hone Claws
- Earthquake
- Substitute
- Reversal
Now with the Sun, Jellicent isn't really good there. You need something for the Rain and Rotom-W.
Latios works well there and can help your Dragon core and it's a nice switch for Skarmory, Forretress and it can kill Scizor and Ferrothorn with Hp Fire.
...
Latios @ Life Orb
Trait: Levitate
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Draco Meteor
- Hidden Power [Fire]
- Recover
- Psyshock
GL with this Team !
