DESCRIPTION:
The Choice Scarf capitalises on Hydreigon's high-speed stat, allowing it to be great speed control. A Speed stat of 98 allows Hydreigon to only be outsped by Salamence, Jirachi, Tentacruel, Thundurus-Therian, Nihilego, Zarude, Keldeo, Latias, Zygarde, Azelf and Regieleki. Nearly all of these Pokémon, given that they are not holding a Choice Scarf as well, do not appreciate Hydreigon’s strong super-effective attacks.
A major advantage Hydreigon has as a revenge-killer and speed control Pokémon over Latias is its wide offensive coverage. Hydreigon’s excessive coverage allows it to become versatile enough to adapt to cover any team’s weaknesses. For instance, Latias fails to attack bulky Fairy and Steel Pokémon, which Hydreigon has ease attacking. Hydreigon’s access to Flamethrower/Fire Blast allows it to reliably check +2 Speed Celesteela, Amoonguss, Roserade, Tangrowth, Tapu Bulu and Zarude. Flash Cannon is excellent to cover Hydreigon’s personal Ice and Fairy weakness, by outspeeding and dealing massive damage to Mamoswine, Hatterene, Togekiss, Tapu Bulu, Diancie, Gardevoir and Sylveon. Earth Power allows Hydreigon to target Lycanroc, Nihilego, Rhyperior, Nidoking, Cobalion and Volcanion. Focus Blast can be used if opposing Dark or Rock-type Pokémon pose a threat to Hydreigon’s teammates. Hydro Pump is an option, though Hydreigon’s STAB moves are arguably more useful.
Draco Meteor is an amazing STAB move that OHKOs or finishes off most sweepers or slower threats, such as Calm Mind boosted Latias, +1 Speed Kommo-O, Life Orb Mienshao, unboosted Salamence, +1 Speed Gyarados, Azelf, Thundurus-Therian, Nidoking, Starmie, Zygarde, Noivern and +2 Speed Polteagiest. Dark Pulse is a reliable STAB attack that is usually a safe option to revenge-kill weakened opponents. Additionally, the 30% flinch chance has the ability to transform the momentum of a match.
Given how the UU metagame has been increasingly focused on hazard stacking, Hydreigon’s Levitate ability granting it immunity to Spikes and Toxic Spikes is beneficial to its role as speed control, increasing its longevity and opportunity to switch in and out constantly with U-turn.
