had a Calm Mind
Despite a fall from grace following the ban of Tangela, Goomy still possesses a few redeeming qualities that grant it a small niche in the ORAS LC metagame. Goomy has good Special Attack and Special Defense stats and is the only Pokemon in Little Cup with access to Gooey; this is an especially nice ability in Little Cup due to an increased emphasis on Speed tiers. Goomy also has access to Sap Sipper, which lets it take on threats such as Snivy and Bellsprout with ease. It is also one of the very few defensive Dragon-type Pokemon in Little Cup, granting it key resistances to Fire, Water, and Grass. However, there is certainly a reason that Goomy was swept under the rug following Tangela's departure. Poor overall base stats keep Goomy from really shining, and its lackluster Defense holds it back from making full use of Gooey. Goomy is unable to hit very hard off of its poor base 55 Special Attack and thus grants many sweepers the opportunity to set up against it. Goomy also lacks any reliable recovery moves, forcing it to rely on Rest to consistently perform well defensively. Finally, the presence of powerful Fairy-types such as Spritzee on many teams often makes Goomy a liability.
name: Gooey Pivot
move 1: Draco Meteor / Dragon Pulse
move 2: Sludge Wave / Hidden Power Fighting
move 3: Rest
move 4: Sleep Talk
evs: 76 HP / 236 Def / 156 SpD / 36 Spe
Goomy's Draco Meteor is so powerful that two Draco Meteors will always outdamage two Dragon Pulses, even with the Special Attack drop. However, Dragon Pulse can be used over it if you foresee staying in on foes for more than two attacks. The second slot is up to you, and is selected based on what you don't want to switch in on Goomy: Sludge Wave hits incoming Fairy-types, whereas Hidden Power Fighting hits Steel-types such as Pawniard. Rest provides the recovery necessary to prolong Goomy's defensive utility. Sleep Talk keeps Goomy from being total setup bait during the two turns of sleep from Rest. However, Goomy is still setup bait for the most part due to its weak attacks and its reliance on picking the correct attacking option to do any meaningful damage.
The listed EV spread and a Bold nature maximize Goomy's Defense and bolster its Special Defense, giving it a spread of 22 / 14 / 16 before Eviolite. The extra EVs are put into Speed, as it is the only remaining stat that can be raised with 36 EVs. However, if you choose to use Hidden Power Fighting, you will have to forgo the Speed EVs with a spread of 76 HP / 240 Def / 160 SpD to maintain the same defensive stats. Eviolite raises Goomy's defenses and is preferred over Berry Juice, as Goomy both needs the increased defenses Eviolite provides to check threats such as Chinchou and already has access to Rest. It is possible to move the 76 HP EVs into Special Attack, then notably scoring a 2HKO on Spritzee with Sludge Wave. However, Goomy is then 3HKOed by attacks such as Timburr's Drain Punch and can no longer beat Snivy without Sap Sipper.
Goomy needs to be at high health to consistently stomach the physical attacks it needs to take to activate Gooey. This entails using Rest often. Goomy can also check special attackers such as Chinchou to an extent due to its naturally high Special Defense and its Dragon typing. It is usually enough for Goomy to switch in, attack once, Rest, and then switch out. Gooey is its main niche and should be used in a pivoting fashion to benefit other slower, more powerful attackers.
It's a good idea to pair Goomy with a bulky physical wall to pivot into after activating Gooey. Ponyta works well in this role, and it can help get around the Fairy-, Steel-, and Ice-types that trouble Goomy. Slow, bulky attackers such as Pancham and Skrelp appreciate the Gooey support Goomy provides; Pancham has the added benefit of beating Steel-types and luring Fairy-types with Gunk Shot, whereas Skrelp beats Fairy-types and lures Steel-types with Hidden Power Fire. Steel-types cover all of Goomy's weaknesses, whereas Goomy does well against Fire- and Fighting-type Pokemon. Magnemite is particularly good in tandem with Goomy, as it can trap and remove Steel-type Pokemon via Magnet Pull, allowing Goomy to run Sludge Wave without issue.
Goomy also has access to Sap Sipper, which can be used in place of Gooey if your team is weak to Pokemon such as Snivy; however, this removes Goomy's most important niche. Goomy can use Hidden Power Fire to lure Ferroseed, but it will not OHKO, and that moveslot is better filled by the two options already presented. With access to Hydration and Rain Dance, Goomy can forgo Sleep Talk to work as a manual rain setter on a rain team. Goomy has a decent Attack stat and can make use of physical attacks such as Outrage and Iron Tail in conjunction with Sap Sipper, but it is heavily outclassed by other more powerful attackers.
Checks and Counters
**Fairy-types**: Even with Sludge Wave for coverage, Goomy struggles to deal with bulky Fairies, such as Spritzee and Snubbull, that can hit it hard with super effective STAB attacks. Note, however, that Sludge Wave is a guaranteed OHKO on Cottonee if Stealth Rock is up.
**Steel-types**: Steel-types have little difficulty coming in on Goomy even if it runs Hidden Power Fighting. Pawniard is especially threatening, as its ability, Defiant, actually grants it an Attack boost when Gooey activates.
**Regenerator**: Goomy's damage output is pretty low; as such, Pokemon such as Mienfoo and Foongus can easily take a Draco Meteor then switch out and heal off the damage via Regenerator.
**Bulky Pokemon**: Once again, Goomy lacks the power to break through bulky Pokemon such as Porygon that easily stomach anything Goomy can hit them with.
**Setup Sweepers**: Goomy's low damage output lets it down once again, leaving it as setup bait for many notable setup sweepers, such as Shell Smash Omanyte and Swords Dance Fletchling.
