I have seen a few lele's with focus blast recently. I'm sure though that av ttar can survive at least one though.
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 252 HP / 252+ SpD Assault Vest Tyranitar: 276-328 (68.3 - 81.1%) -- guaranteed 2HKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Moonblast vs. 252 HP / 252+ SpD Assault Vest Tyranitar: 164-194 (40.5 - 48%) -- 58.6% chance to 2HKO after Stealth Rock
AV Tyranitar can't switch into specs Tapu lele because it is 2HKO'd if it predicts incorrectly.
I still like using Shadow Ball and Focus Blast on Tapu Lele as it makes her completely "unwallable". Shadow ball is a nice option for hitting Gross and Jirachi super effectively. Thunderbolt and Hp fire definitely have their uses though as seen in the calc's. Psyshock can hit some things just as hard as what super effective T-Bolt can (will show on Manaphy calc).
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 248 HP / 192+ SpD Heatran: 314-370 (81.5 - 96.1%) -- 56.3% chance to OHKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Psyshock vs. 248 HP / 0 Def Heatran: 154-182 (40 - 47.2%) -- 1.2% chance to 2HKO after Stealth Rock and Leftovers recovery
Despite how crazy this calc is, Tapu Lele can't quite 2hko Heatran with specs Psyshock.
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 252 HP / 168 SpD Ferrothorn: 328-388 (93.1 - 110.2%) -- 93.8% chance to OHKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Shadow Ball vs. 252 HP / 252+ SpD Jirachi: 208-246 (51.4 - 60.8%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 252 HP / 252+ SpD Jirachi: 155-183 (38.3 - 45.2%) -- guaranteed 3HKO after Stealth Rock and Leftovers recovery
Focus blast clearly can not 2hko SpDef Jirachi...
252+ SpA Choice Specs Tapu Lele Hidden Power Fire vs. 252 HP / 252+ SpD Jirachi: 156-184 (38.6 - 45.5%) -- guaranteed 3HKO after Stealth Rock and Leftovers recovery
Jirachi can handle Hp fire easily so shadow ball is better for this.
252+ SpA Choice Specs Tapu Lele Shadow Ball vs. 0 HP / 0 SpD Metagross: 314-370 (104.3 - 122.9%) -- guaranteed OHKO
(Metagross doesn't get its buffed SpDef on switch in)
252+ SpA Choice Specs Tapu Lele Hidden Power Fire vs. 0 HP / 0 SpD Metagross: 236-278 (78.4 - 92.3%) -- guaranteed 2HKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 0 HP / 0 SpD Metagross: 235-277 (78 - 92%) -- guaranteed 2HKO after Stealth Rock
Shadow ball is better on Metagross because it OHKO's on the switch in and can't KO back by out speeding on the following turn.
Celesteela is one of the best switch ins to Specs Tapu Lele running Focus Blast and Shadow Ball. Even then, Psyshock hits Celesteela harder than Focus Blast if it is max SpDef.
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 252 HP / 252+ SpD Celesteela: 153-181 (38.4 - 45.4%) -- 12.5% chance to 2HKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Psyshock vs. 252 HP / 0 Def Celesteela: 158-186 (39.6 - 46.7%) -- 35.5% chance to 2HKO after Stealth Rock.
252+ SpA Choice Specs Tapu Lele Hidden Power Fire vs. 252 HP / 252+ SpD Celesteela: 154-182 (38.6 - 45.7%) -- 14.1% chance to 2HKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Thunderbolt vs. 252 HP / 252+ SpD Celesteela: 230-272 (57.7 - 68.3%) -- guaranteed 2HKO after Stealth Rock
With only leech seed as recovery, Celesteela is a very shaky switch in to Tapu Lele not even running T-bolt or HP Fire. Sure Specs Thunderbolt will easily 2hko Celesteela, the trade off against missing the OHKO on Metagross and 2HKO on Jirachi in my opinion is not worth it. Especially when Celesteela is straight up 2hko'd by Psyshock with the tiniest bit of prior damage. Hp Fire does less than Psyshock.
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 0 HP / 0 SpD Magnezone: 470-554 (167.2 - 197.1%) -- guaranteed OHKO
252+ SpA Choice Specs Tapu Lele Hidden Power Fire vs. 0 HP / 0 SpD Magnezone: 236-278 (83.9 - 98.9%) -- 37.5% chance to OHKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 252 HP / 252+ SpD Skarmory: 194-229 (58 - 68.5%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery (sets lacking Hp Fire and T-Bolt can already 2HKO Skarm, just not as reliably.
252+ SpA Choice Specs Tapu Lele Thunderbolt vs. 0 HP / 0 SpD Manaphy: 324-382 (95 - 112%) -- guaranteed OHKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Psyshock vs. 0 HP / 4 Def Manaphy: 322-379 (94.4 - 111.1%) -- guaranteed OHKO after Stealth Rock
Psyshock can already get a guaranteed OHKO on Manaphy after rocks!
252+ SpA Choice Specs Tapu Lele Psyshock vs. 252 HP / 252+ Def Mantine: 291-343 (77.8 - 91.7%) -- guaranteed OHKO after Stealth Rock
Obviously T-bolt is a OHKO but is it really mandatory to get the OHKO on this thing when psyshock already does so much damage to it? Scald doesn't
do much back to Lele.
252+ SpA Choice Specs Tapu Lele Psyshock vs. 4 HP / 252+ Def Eviolite Chansey: 429-505 (66.8 - 78.6%) -- guaranteed 2HKO after Stealth Rock
Psyshock allows the easy 2HKO on Chansey.
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 248 HP / 200 SpD Scizor-Mega: 178-210 (51.8 - 61.2%) -- guaranteed 2HKO after Stealth Rock
252+ SpA Choice Specs Tapu Lele Hidden Power Fire vs. 248 HP / 200 SpD Scizor-Mega: 360-424 (104.9 - 123.6%) -- guaranteed OHKO
252+ SpA Choice Specs Tapu Lele Hidden Power Fire vs. 248 HP / 200 SpD Scizor-Mega: 360-424 (104.9 - 123.6%) -- guaranteed OHKO
252+ SpA Choice Specs Tapu Lele Psychic vs. 248 HP / 200 SpD Scizor-Mega: 150-177 (43.7 - 51.6%) -- 99.6% chance to 2HKO after Stealth Rock
Hp Fire is better here but Focus can still 2HKO if you get lucky and hit twice. Scizor can't bullet punch you back in terrain. Psychic being a 2hko after rocks is disgusting.
252+ SpA Choice Specs Tapu Lele Psyshock vs. 96 HP / 0 Def Tornadus-Therian: 390-459 (120.7 - 142.1%) -- guaranteed OHKO
252+ SpA Choice Specs Tapu Lele Psychic vs. 96 HP / 0 SpD Assault Vest Tornadus-Therian: 264-312 (81.7 - 96.5%) -- guaranteed OHKO after Stealth Rock
You can just OHKO a Torn-T from full without Stealth Rock when not using Psychic.
Just to show how beast this thing is...
252+ SpA Choice Specs Tapu Lele Psyshock vs. 252 HP / 4 Def Klefki: 174-205 (54.7 - 64.4%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
252+ SpA Choice Specs Tapu Lele Hidden Power Fire vs. 252 HP / 252+ SpD Klefki: 170-202 (53.4 - 63.5%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
252+ SpA Choice Specs Tapu Lele Psychic vs. 252 HP / 252+ SpD Klefki: 143-168 (44.9 - 52.8%) -- 28.9% chance to 2HKO after Stealth Rock and Leftovers recovery
252+ SpA Choice Specs Tapu Lele Focus Blast vs. 252 HP / 252+ SpD Klefki: 170-200 (53.4 - 62.8%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
Magearna is just 2HKO'd by Focus Blast and Hp Fire as well.
So yeah, Tapu Lele is almost impossible to reliably switch into (edit: Clair mentioned AV Muk)
If Tapu Lele predicts correctly and goes for Moonblast Muk loses 29.7 - 35%, a 3hko after rocks. Tapu Lele can just stay in and fire off another Moonblast. If Muk goes for Pursuit it does only 20.6-24.5%, allowing Tapu Lele to fire off another one and finishing Muk off. Obviously this is in Muk's favour since it can OHKO with Gunk Shot and punish choice locked psychic STAB, but it is hardly reliable. Muk may not be a complete pushover, but I daresay there are much better Pokemon in OU that one would want to spend a valuable team slot on.
0 Atk Muk Pursuit vs. 0 HP / 0 Def Tapu Lele: 58-69 (20.6 - 24.5%) -- guaranteed 5HKO
If Lele switches Muk does less than half with Pursuit, meaning Lele is free to try and do damage again later.
Compared to Hoopa U, it's Psyshock hits harder, it's immune to priority, is faster, and has better defensive typing. Hoopa U has the edge with power on it's coverage moves, ability to go physical and slightly better SpDef. I think Tapu Lele is a complete monster and sadly it will inevitably get banned. It's just way too much for OU. I haven't even mentioned yet how good the scarf set is but it is phenomenal. A scarfer immune to priority is just insane, especially a special attacker that can 2HKO Chansey after stealth rock!
252+ SpA Tapu Lele Psyshock vs. 4 HP / 252+ Def Eviolite Chansey: 286-337 (44.5 - 52.4%) -- guaranteed 2HKO after Stealth Rock
For those saying they think that a choice item is not a good idea on Tapu Lele because Dark Types can take advantage with pursuit have clearly forgotten what set it was that pushed Hoopa-U over the edge last gen. Psssst... It was specs.
