Tapu Lele @ Choice Specs
Ability: Psychic Surge
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Psychic
- Moonblast
- Thunderbolt
- Shadow Ball
This Tapu Lele is a huge threat against this team for the following reasons:
- Lack of any proper switch-ins
- Victini can neither out-speed nor OHKO Tapu Lele - two feats which it is usually capable of doing
- Corviknight isn't holding Leftovers and it isn't specially defensive either
- As a bonus, Tapu Lele even 1v1s M-Lopunny which limits revenge killing options to Kartana
Psychic is extremely spammable against this team, most notably having a 79.3% chance to 2HKO Corviknight after Stealth Rock, and doing 42.4 - 50.2% to Victini.
252+ SpA Choice Specs Tapu Lele Psychic vs. 252 HP / 72 SpD Corviknight in Psychic Terrain: 165-195 (41.2 - 48.7%) -- 79.3% chance to 2HKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Psychic vs. 116 HP / 0 SpD Victini in Psychic Terrain: 157-186 (42.4 - 50.2%) -- 0.4% chance to 2HKO
Thunderbolt and Shadow Ball are simply there to improve the 1v1 situation against Corviknight and Victini respectively. As switch-ins, you can clearly see they are easily overwhelmed by Psychic. The unorthodox EV spread on Victini means it can't out-speed even a Modest Tapu Lele, and the lack of V-Create means it can't OHKO either. This makes the matchup significantly easier for Tapu Lele, as it can even opt to stay in once Victini switches in and finish it off with a third Psychic, tanking one Blue Flare in the process.
Corviknight is susceptible to SpDef drops or crits, or of course a simple Thunderbolt prediction which would do 85-100.5%, effectively rendering Corviknight dead. Just for completion's sake, I'll show the calc for Shadow Ball against Victini too.
252+ SpA Choice Specs Tapu Lele Thunderbolt vs. 252 HP / 72 SpD Corviknight: 340-402 (85 - 100.5%) -- 6.3% chance to OHKO
252+ SpA Choice Specs Tapu Lele Shadow Ball vs. 116 HP / 0 SpD Victini: 288-340 (77.8 - 91.8%) -- guaranteed 2HKO
It helps that Kartana, the one Pokemon that can reliably revenge kill Tapu Lele cannot switch in to literally any move from Tapu Lele, so this Tapu Lele effectively gets a kill every time it comes in by clicking Psychic. If Stealth Rock is not set, you only need to make one easy-to-make prediction of Thunderbolt-ing the Corviknight, assuming it hasn't taken any prior damage already.
I'd just like to disclose I'm completely new to this so if I didn't follow any rules, please let me know. I know Specs Tapu Leles would favour Psyshock to blow past the blobs, but I dropped it on mine to improve the matchup against the team. If our sets need to be a bit more realistic for general play, then I'd say drop Shadow Ball for Psyshock for a more realistic set. Psyshock also has the benefit of ignoring a potential Calm Mind boosted Tapu Fini.
