Coral bleaching is a real problem in the reefs around the world no thanks to climate change and the population explosion of crown of thorns starfish (Toxapex), and it seems GameFreak got the word out about this serious environmental problem by creating a very unnerving Galarian variant of a gen 2 Pokemon widely considered to be useless in the competitive scene. Ironically enough, making Galarian Corsola far more viable will probably only make trainers want the reefs to die off faster in apocalyptic waves:
Anyways, G. Corsola is better than its pink cousin thanks to better defensive typing, more crippling moves like Will-O-Wisp, access to Strength Sap, and because it gets an evolution which means it gets a powerful fully evolved form as well as a defensive pre-evolved form thanks to Eviolite. So let's get straight into the nightmare fuel that is Cursola and its pre-evolution.
Trick Room or Treat
Ability: Perish Body
Item: Choice Specs
Nature: Quiet (+Sp.Attack -Speed)
EVs: (HP 252) (Def 4) (Sp.Attack 252)
IVs: (0 Speed)
Moves:
Shadow Ball
Ice Beam/Hydro Pump/Giga Drain/Earth Power/Burning Jealousy
Set Details:
Cursola's speed is...terrible. Seriously, GF should have at least given it respectable physical defenses to compensate, but nooooooo they just had to make it slow AND physically frail. They could have at least given it Trick Room to compensate, but apparently it isn't as Ghost-like as Dusknoir and Runegrigus to justify it. XP So Cursola will be dependent on teammates to set up Trick Room for it. Choice Specs boost its base 145 special attack even higher, and thankfully Cursola has a very wide offensive movepool to make use of. Shadow Ball is a given, but the other three moves are a matter preference. Ice Beam targets Dragons, Hydro Pump has excellent power, Giga Drain punishes defensive Water/Ground types AND offers a form of recovery, Earth Power targets a wide range of types for super effective damage, and Burning Jealousy is a nasty surprise for Ferrothorn and the Bug/Steels. All EVs and nature get put into special attack and HP while all efforts are made to keep Cursola's speed as slow as possible to best utilize Trick Room. Also, go with Perish Body as the ability since the unexpected speed boost after surviving a physical attack will ruin the reliance on low speed. Just don't expect the Perish Song effect when it activates to be all that useful outside of forcing switches.
Evil Eviolite
Ability: Cursed Body
Item: Eviolite
Nature: Bold (+Defense -Attack)
EVs: (HP 252) (Def 156) (Sp.Def 100)
Moves:
Will-O-Wisp
Hex/Night Shade
Strength Sap
Whirlpool
Set Details:
Let's be honest. Everyone is going to use G. Corsola over Cursola thanks to far better usage as an Eviolite wall than as a slow and frail sweeper. How ironic that Corsola is now sitting in the same club as Toxapex as one of the game's best defensive Pokemon despite the entire reason for it being there is because it was probably eaten by that very same Toxapex. Yesterday's prey is now today's defensive teammate. Will-O-Wisp ruins physical attackers and does residual damage over time. Your choice of offensive move is a toss-up really since Hex synergizes well with Will-O-Wisp's burn and gives G. Corsola some decent fire power despite the low base special attack, and Night Shade is consistent and reliable damage. The former works better on frailer targets while the latter is better on defensive ones. Strength Sap is leagues better than its Johto cousin's Recover since it almost always heals more than 50%, all while dropping your opponent's physical attack in the process, granted special attackers may present a more difficult survival issue. The last slot is actually an original choice from yours truly, and I have had a great deal of success with Whirlpool. Not only does it keep your opponent from switching in a counter, but it also eats away 1/8 of your opponent's health each turn, thus hastening your opponent's demise. Ability goes to Cursed Body since Weak Armor's defense drop is crippling to a defensive Pokemon and the speed boost is not worth it. Conversely, the chance of disabling one of your opponent's moves with Cursed Body is an added bonus that can keep your opponent from using its best moves against you. Eviolite is integral to giving G. Corsola the extra defense it needs, and the nature and EVs are similarly poured into bulk. So yeah, G. Corsola is a top tier threat that everyone should be prepared to face. Though I still think it's kind of sad that it took killing the poor pink coral boi for anyone to love it...
Also, I can't be the only one who thinks Galarian Corsola's design looks like something stright out of a Creepypasta right? (
