This is the Choice Scarf set that Gyarados uses on Flying teams in Gen 9 Monotype. Waterfall is used as Gyarados ' Water STAB that has a chance to flinch opposing Pokemon. Earthquake provides coverage against Pokemon such as Toxapex, Gholdengo, Clodsire, Kingambit, and Iron Hands. Thunder Wave is used to slow down opposing Pokemon. Iron Head provides coverage against Chien-Pao and Fairy-types in general. Crunch provides coverage against Ghost- and Psychic-types such as Brambleghast, Hisuian Zoroark, Indeedee, and Slowbro. Intimidate is the usual Ability used on this set to force switches, though Moxie is fine if you prefer to have Gyarados have potential to snowball through opposing teams.
You're probably thinking that I should replace Thunder Wave with another move since this is a Choice Scarf set, but Scarf Thunder Wave is useful and is actually a thing in the current Monotype meta for a couple reasons. 1.) Flying teams as of now aren't as fast as they were in Gen 8 Monotype, so Flying teams appreciate the utility of Thunder Wave slowing down opposing Pokemon. 2.) Thunder Wave slowing down opposing Pokemon allows Gyarados to slow down Choice Scarf users who would otherwise outspeed Choice Scarf Gyarados.
