This is the team i got the most mileage out of in ADV Cup as it just generally has a great matchup vs a lot of things. The core of Aipom + Clamperl can break through opposing stall/balance while the rest of the defensive backbone checks almost the entire meta. Aipom used to be banded on this team but I changed it to this set about half way through the tour as it has a fantastic match up vs almost every common lead except Minun and is much less prediction based than Band. The aim of this set is to effectively break down normal resists. Aipom subs on most offensive leads that fear the strong normal stab. Once behind a sub on the standard normal resists in the tier like Shuckle and Duskull, Aipom can pass to DeepSeaTooth Clamperl to bring it in safely to start breaking. HP Grass is the filler move of choice to 2hko lead Omanyte, Onix, and threaten Corsola, Marshtomp, Rhyhorn, etc. The rest of the team forms the defensive backbone of the team. Shuckle checks normals and cripples setup sweepers with Encore + Toxic. Marshtomp checks DD Dragonair and offensive rock types like Rhyhorn and Anorith. Ivysaur is here to absorb Toxic as well as check electrics and Waters. The last slot has changed a lot but it has always been the dedicated fire check. During the ADV Cup, I used a few different variations of spdef CroSparce (rip snek). When it was banned, I swapped to Drowzee which can beat pretty much every fire type 1v1 with its sheer bulk but is quite vulnerable to toxic and encore/taunt. Psychic helps you check Combusken a bit better and gives you a way of touching Gastly but Toxic is also an option to do standard Toxic things. Spdef Dragonair is what I've been using more often as it is less susceptible to Toxic/Encore/Taunt and just generally has more offensive presence but is significantly less bulky. Thunder Wave lets you slow down offensive threats and give Clamperl an easier time, but Thunderbolt can also be used for hitting waters like Sealeo and Corsola as well as giving you a way of hitting fire types for neutral damage.
