Goodra-H is known for standing in the way of many prominent special threats, such as Enamorous, Tran, and the like. However, it has always lacked a certain level of threat in its game; simply Toxic is not enough. This is where Curse comes in. Curse allows Goodra to actually pose a threat to the other team, reminding them that it is not just a passive blob. Heavy Slam is the primary STAB, since Goodra is one hell of a hefty boi. Dragon Tail is a great dragon STAB, as it provides shuffling, which is great on hazard heavy teams, and its negative priority is nonexistent due to Curse already lowering speed. However, Dragon Claw is a slightly more powerful move. Finally, Body Press abuses the Defense boosts gains from Curse, and with Tera Fighting, it can hit for tons of damage. Max HP and SpDef ensures that, with enough Curses, both Defenses would be extremely high, allowing for a successful bludgening session.
Goodra appreciates Fighting types removed so their Close Combats won't come flying about, so mons like Enamorous and Valiant do the trick. Because of its ability, Sap Sipper, Goodra can also benefit from Grass moves aimed towards its teammates, notably Rillaboom's Grassy Glide. A teammate like Greninja should do the trick. Rillaboom itself can also act as a good teammate, as it neuters stray Earthquakes from the likes of Defensive Tusk and Lando. Lastly, Hazard support, while not mandatory, helps make up for Goodra's relatively underwhelming attack along with little invest. It is up to choice whether to use a suicide lead, like Glimmora, or use a bulkier mon, like Ting-Lu.
This Goodra thrives in more offensive teams, as they do appreciate such a tanky Pokemon to fall back on, yet they also appreciate that it itsn't very passive. However, it is not recommended for this Goodra to be used on Hyper Offense, as their fast-paced style means that Goodra would be heavily disrupting the pace that they would normally play at. Goodra doesn't fit on stall, either, as it lacks the longevity needed to be part of the team, especially after it has taken many hits setting up Curses.
