Ice Steel E4 Warden Region

Wirlixin (Metagross) @ Metagrossite
Ability: Clear Body
Shiny: Yes
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Meteor Mash
- Hammer Arm
- Zen Headbutt
- Ice Punch

Standard Mega Meta - Cleans up late game once faster Pokémon has been taken cared off, or paralyzed. Mash+Zen for STAB, Ipunch for Lando-T etc and Hammer Arm that kills certain Pokémon that Mash cannot.

Niermourn (Kyurem-Black) @ Leftovers
Ability: Teravolt
Shiny: Yes
EVs: 56 HP / 252 SpA / 200 Spe
Mild Nature
- Ice Beam
- Fusion Bolt
- Earth Power
- Substitute

Standard Sub set - Used to take care of annoying Pokémon that likes to status, as well as taking electric attacks that my other Pokémon hates to take. Retains its Sub against Chanseys among things. Sub on a predicted switch and 2HKO certain Pokémon at will, or get free damage off at least.

Depression (Skarmory) (M) @ Rocky Helmet
Ability: Sturdy
EVs: 248 HP / 252 Def / 8 SpD
Bold Nature
IVs: 0 Atk
- Whirlwind
- Defog
- Stealth Rock
- Roost

Main DEF wall and also my stealth rocker & phazer. Removes annoying hazards on my end of the field as well since I need both my Kyurem and Lapras healthy. Sticky Web also means a guaranteed loss depending on my opponent, thus Defog is crucial above all else. This set is prone to be taunted, so i'm considering changing Stealth Rocks to Counter and give Meta Stealth Rocks instead.

Reignsun (Heatran) (M) @ Choice Scarf
Ability: Flash Fire
EVs: 28 HP / 252 SpA / 228 Spe
Timid Nature
- Lava Plume
- Flash Cannon
- Earth Power
- Stone Edge

Standard scarf set with Lava Plume over Overheat. Trading raw power for the chance of burning my opponent, and using Stone Edge over Ancient Power to OHKO Char Y & Volcarona. Heatran is also a necessity due to the Fire immunity that I am otherwise incredibly weak to. I can easily switch up Choice Scarf to Kyurem-B for better revenge killing against more Pokémon and make Heatran a Stallbreaker as I am primarily weak to Chansey+Blissey and other certain Stall Pokémon.

Nimilie (Lapras) (F) @ Chople Berry
Ability: Water Absorb
EVs: 112 HP / 252 SpA / 144 Spe
Modest Nature
IVs: 0 Atk / 30 SpA / 30 Spe
- Hydro Pump
- Freeze-Dry
- Heal Bell
- Hidden Power [Fire]

My own custom set. This Lapras is my sure way of checking Keldeo and revenge killing other Fighting Types thanks to Chople Berry and access to Heal Bell to remove status that otherwise completely cancels out my team overall... With burn being nerfed, it wont be much of a hazzle, along with paralyze nerf... Will experiment to see if I still need Heal Bell or not. As of now, it stays. HP Fire is mandatory against Skarmory, Ferrothorn, etc that otherwise laughs at my team in the long run.

Jirachi @ Leftovers
Ability: Serene Grace
EVs: 252 HP / 224 SpD / 32 Spe
Careful Nature
- Iron Head
- Body Slam
- Wish
- Protect

My main wish passer and my spdef wall. Laughs at Cloyster where some people for some reason uses Surf... (What?) Body Slam to paralyze and then proceed to Paraflinch like the little filth I am. A paralyze on certain Pokémon like Hydreigon, Scarf'd Nidoking, etc can be crucial overall, otherwise they just completely roflstomp my team entirely.
