Here's my team:
Ribombee @ Focus Sash
Ability: Shield Dust
Shiny: Yes
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Sticky Web
- Moonblast
- Hidden Power [Fire]
- Stun Spore
This one's role should be self explanatory, come in first, set up webs, spit on most other leads and offensive mons with stun spore, the webs are crucial for outspeeding most scarf mons with gyarados or magearna provided they're set up.
Gyarados @ Gyaradosite
Ability: Intimidate
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Dragon Dance
- Crunch
- Waterfall
- Earthquake
One of my two win cons on this team, Intimdate allows it to set up on quite a few physical mons like Mega Sciz and Lando-t, those webs ensure it outspeeds almost everything once it sets up and it can lay quite the hurt on the special walls like chansey that would steamroll everything on this team otherwise bar excadrill, its typing lets it, as far as I know, switch in on tran and most other fire types and steel types in the tier, which can provide other teammates some breathing room if it needs to switch in. This mon is usually used right after mag has run through the opposing team, It can also be used vice versa, letting mag clean after instead.
Serperior @ Leftovers
Ability: Contrary
Shiny: Yes
EVs: 56 HP / 200 SpA / 252 Spe
Timid Nature
- Leaf Storm
- Hidden Power [Fire]
- Substitute
- Leech Seed
A sticky web team wouldn't be complete without serp, with webs up serp outspeeds pretty much everything except for some mons like tornadus T and some scarf flying types. With leaf storm and contrary serp can become a real pain to switch into and demolish most walls except for some extremely bulky fat mons like chansey. This mon is capable of cleaning a team after a sweep from m-gyarados or mag have ran through it, or alternatively it can soften up walls before Mag or Gyarados run through it, which can make the sweep much easier. Subseed helps ruin braindead mons like celesteela which can't really hurt serp for much damage and allow it to set up on them, it does get trolled hard by tran and a lot of other grass resists but hp fire can help alleviate that against mega sciz and ferrothorn, tran can also be dealt with by zygarde or excadrill, or sometimes gyarados as well.
Magearna @ Fightinium Z
Ability: Soul-Heart
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Shift Gear
- Fleur Cannon
- Thunderbolt
- Focus Blast
My second major win condition, this one is more for late game than early, fightinium Z is the item of choice here because it allows it to nuke ferrothorn and heatran right off the bat, OHKOing tran and heavily denting ferrothorn, in which thorn can't really do much to you anyways so its as good as dead to you, it also has the bonus of doing loads more to chansey if you have some soul heart boosts under your belt, a +1 all out pummeling and a focus blast immediately after has a real good chance of killing it off after SR damage if not outright killing it off. You do lose to pex easier without boosts but that isn't really anything that Excadrill, zygarde or even serp can't deal with earlier on.
Zygarde @ Choice Band
Ability: Aura Break
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Thousand Arrows
- Extreme Speed
- Iron Tail
- Outrage
My main physical wallbreaker, banded thousand arrows trolls all levitating and flying types as well as OHKOing or 2HKOing most of them, much like serp, nothing wants to switch into this monster bar some grasses and bugs, even then the grasses bar bulu and thorn have to be cautious of outrage utterly demolishing them, and which iron tail hits bulu and thorn gets hit hard by thousand arrows, webs help zygarde quite a bit but not as much as mag and gyarados, with webs up it can get the drop on mons like gren and koko. Basically zygarde's goal is to soften the team up early game for its team mates to run over later on.
Excadrill @ Focus Sash
Ability: Mold Breaker
Shiny: Yes
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Stealth Rock
- Rapid Spin
- Earthquake
- Toxic
Usually the suicide lead after ribombee, it gets up rocks and rapid spins away the opposing hazards. It can provide a real good way to break or get rid of mons that can ruin this team like tran and pex, it can provide crucial resistances to fairy spam and prevents lele and koko from being a nuisance. The rocks it sets up give the set up sweepers and wallbreakers a real hard time with switching in repeatedly.
