Zard X Fire Spam Bulky Offense w Weavile Pursuit Support
Fire types are a cornerstone attack type in SM metagame and Zard X is a top tier abuser of fire attacks. With that, the obvious thing to do is stack fire type attackers that synergize together positionally and enable that concept as much as possible with support pieces. Serperior and Heatran stack fire moves to create fire spam core. Weavile+Fini attack dragons that attempt to stop fire spam core from destroying the opponent. Lando T provides many needed roles in a pivot move, volt switch blocker, defensive buffer, backup defog, revenge killer and adds a strong EQ to pair with Zard X. Bam, team is done.
Heatran
* Stealth rocks are great at chipping down opponents and punishes switches, best move in pokemon. Taunt+toxic deters many dynamics unfavorable to fire+ice+ground core like stealth rocks, set-up, water and ground attackers among other generally useful ways to use those moves. Since Heatran has Fini+Zard X+leech seed support, there's less of a need to use earth power to take out Toxapex and Heatran while toxic covers other swap ins. Fire blast is a generally strong fire move with decent accuracy, stacking on the fire attacking core even more.
* 2hko 248 HP Lando T from full without rocks up (assuming no leftovers). Speed is faster than jolly Bisharp+EV point jump. Rest is dumped into HP to allow Heatran to be more defensively capable into brokens like Mega Mawile, Volcarona, Magearna and Tapu Lele.
Serperior
* Leaf storm+HP fire is a great attack combination in tandem with leech seed to chip away at steels, flying and dragon types that try checking Serperior. Chipping those pokemon down allow ground and ice attackers to be fully enabled. Leech seed also provides some recovery to its teammates and creates switch opportunities, deadly with pursuit support+substitute.
* Always eats Rotom W hydro pump uninvested with sub up. Rest dumped into speed+special attack power to maximize Serperior's offensive output.
Zard X
* Flare blitz+earthquake creates the core attack types this team hinges on. Roost creates much needed longevity for Zard X to continue its flare blitz onslaught. With misty terrain support and no dragon claw, there is zero downside for Zard X to be under terrain. This allows for swap ins against toxic pex and t-wave Clefable while enabling attacks into static Zapdos. Weavile's pursuit support+stab ice attacks allows Zard X to break past Mega Latias, Dragonite and Garchomp more comfortably. All of this support is there to enable dragon dance as the last slot and turns Zard X into a hyper consistent killing machine while being hard to revenge kill.
* With decent natural bulk and its role as the main attacker, max attack and speed is ideal for its role.
Weavile
* Pursuit+ice attacks enables ground+fire attackers to be maximized as dragons that resist/immune to ground attacks are vulerable to pursuit+ice attacks. Ice shard priority as priority keeps in check many breakers/sweepers and unexpected outcomes to have some counterplay.
* Max speed max attack is ideal as Weavile's role is entirely based on its offensive output to enable Zard X+Serperior.
Lando T
* EQ stacks with Zard X for ground attack core. U-turn is a pivot move to bring in Zard X+Serperior+Weavile offense trio. Defog removes hazards to help rock weak Zard X+Weavile swap in more often. Stone edge created edgequake combination that's very difficult to stop generating progress.
* Spread outspeeds +1 Kommo-o, lives Hawlucha +1 acro after rocks, rest into attack.
Tapu Fini
* Misty terrain allows swap ins against passive pokemon, letting the breaking core do what they want. Surf, with the special attack investment, can punish Gliscors attemping to set up and sweep with a over 2/3 chance to 2hko. Surf also lets Fini punish the fires and grounds it'll match up against like Heatran, Volcarona and Lando T. Moonblast is a fairy move that punishes dragons, a big deal for the fire spam core, that also lets Fini beat Mega Medicham and Mega Lopunny 1v1. Natures madness is great general chip damage and keeps opponents honest when swapping around mons in advance to keep the breaking core from coming in. Defog clears hazards that bother the breaking core.
* Enough spedef for Ash Gren pumps (never 3hko'd), enough special attack to have great odds vs SD Gliscor set-up, enough speed for CB Crawdaunt and rest put into physdef for maximum defensive capabilities into fighters like Mega Medicham and Mega Lopunny.
