Tentacruel HazardStack
Peace be upon y'all. Today, I'd like to present a team I've put together for this week's teambuild challenge, which features Tentacruel. Tentacruel is a very underappreciated Pokemon in ORAS OU, and in my opinion, it is an excellent Pokemon in Spikestack since it can provide Rapid Spin, Toxic Spike, ice resistance, absorb Toxic Spike and the ability to check Volcarona's SubSwarm set and Clefable that lacks Thunderbolt.
Skarmory is the second member of this team since it creates a strong hazard stacking core with Tentacruel and can punish Excadrill with Rocky Helmet.
The third Pokemon in this squad is Chansey, because he provides Stealth Rock and Skarmory values Chansey's ability to check most fire types such as Heatran, Volcarona, Mega Charizard Y, and Volcanion.
The reason Clefable is the next member for this squad is because it provides fighting resistance. Furthermore, Clefable also greatly appreciates hazard stack because it can wear down its check, such as Excadrill and Heatran.
Gastrodon is listed as the next Pokemon because it has two immunities: electric and water.
Last but not least, Mega Lopunny is added because it provides speed control.
Edit : I use Power-Up Punch over Quick Attack for better offensive presence. I also use ice beam Clefable for better matchup against Gliscor.
