Qwilfish
Abilities: Swift Swim / Poison Point
Base Stats: 65 HP / 95 Atk / 75 Def / 55 SpA / 55 SpD / 85 Spe
Qwilfish can be seen as a support and offensive threat. Though weak on the defensive side, it has a useful movepool, typing, and offensive stat that give it many options. It has a good offensive typing with STAB Water/Poison which is unresisted by all except itself. It functions as a supporter, and a sweeper in and out of Rain Dance. Its common moves include: Taunt, Spikes, Waterfall, Swords Dance, Poison Jab, Aqua Jet, and Explosion. It's most frequently seen as a lead support Pokemon that runs Taunt, Spikes, Waterfall, and Explosion which shuts down most set up leads as well as setting up itself. Its ability Swift Swim allows it to double its Speed in rain, makin it become a potent sweeper as soon as it switches in during rain. The rain sweeper is usually seen as an inferior to Kabutops, but with the moves Swords Dance, Waterfall, Poison Jab, and Explosion it plays a whole different role not being walled by bulky grass types and having explosion at its disposal.
Rhyperior
Abilities: Lightningrod / Solid Rock
Base Stats: 115 HP / 140 Atk / 130 Def / 55 SpA / 55 SpD / 40 Spe
115 base hp coupled with massive attack and solid defense give Rhyperior the ability to be a an offensive, and support threat. Ground/Rock typing gives Rhyperior STAB Quake/Edge which allows it to power through the metagame. Rhyperior is most commonly seen abusing its versatile movepool and physical power to counter the strong flying types of the tier while setting up stealth rocks and hitting back with overpowered stab moves. Most commonly seen at Rhyperiors disposal are the moves Earthquake, Stone Edge, and Megahorn followed by either stealth rocks, rock polish, substitute, or roar on rare occasions. If Rhyperior is seen carrying support moves such as stealth rocks it will be played more as a defensive pivot, but if rock polish or substitue are seen its goal is to power through teams to open holes for other sweepers.
Weezing
Ability: Levitate
Base Stats: 65 HP / 90 Atk / 120 Def / 85 SpA / 70 SpD / 60 Spe
Poison typing coupled with levitate allows Weezing to have a unique niche that allows it to switch into Ground and Fighting types as well as grass types most notably rhyperior, hitmonlee, and venusaur respectively. Weezings dominant prescense in the metagame is to counter Venusaur by running a rest sleep talk set. By resisting both stabs and being able to take sleep Weezing can be seen as the metagames number 1 Venusaur check. Its 120 base defense, unique resistences and Will-o-Wisp also allow it to provide utility and support against all physically based threats. Sludge bomb, Rest, Sleep Talk, Will-o-Wisp, Haze, and Pain split are the moves that should be anticipated for weezing, while the latter two are rather rare.
fixed stuff up to mirror the metagame now. probably needs more work, ill try and fix it up but if someone else catches stuff feel free to change it.
