Regieleki Calcs

Regieleki
If he does any damage besides this then the plan is to get in Zapdos and Defog him. If your damage with Fake Out is lower than what's written here then he is the Light Clay dual screens set and very likely have Explosion. There's other sets he can run that I'll write down for you. He can also carry a desperation move Hyper Beam, I've included that. Most of the strats for Hyper Beam involve swapping to Gengar after getting in a hit

Zapdos
252+ SpA Choice Specs Transistor Regieleki Thunder vs. 248 HP / 0 SpD Zapdos: 403-475 (105.2 - 124%) -- guaranteed OHKO
252+ SpA Choice Specs Transistor Regieleki Volt Switch vs. 248 HP / 0 SpD Zapdos: 256-303 (66.8 - 79.1%) -- guaranteed 2HKO
252+ SpA Choice Specs Transistor Regieleki Thunderbolt vs. 248 HP / 0 SpD Zapdos: 331-390 (86.4 - 101.8%) -- 12.5% chance to OHKO
252+ SpA Choice Specs Regieleki Swift vs. 248 HP / 0 SpD Zapdos: 98-116 (25.5 - 30.2%) -- guaranteed 4HKO
252+ SpA Choice Specs Regieleki Hyper Beam vs. 248 HP / 0 SpD Zapdos: 245-289 (63.9 - 75.4%) -- guaranteed 2HKO

Zapdos does NOT stay in on this. If your health is high then the best you can do is try to Roost off a Volt Switch so that you don't have to send in another Mon to die or be trapped, like him Volt Switching on Tangela to send in Moltres

If he Hyper Beams you then you will Roost and swap to Gengar if Regi is Specs, if not then go Tangela

Kangaskhan
Thunder and Thunderbolt both kill
252+ SpA Choice Specs Transistor Regieleki Volt Switch vs. 0 HP / 4 SpD Kangaskhan: 282-333 (80.3 - 94.8%) -- guaranteed 2HKO
252+ SpA Choice Specs Regieleki Swift vs. 0 HP / 4 SpD Kangaskhan: 107-127 (30.4 - 36.1%) -- 51.8% chance to 3HKO
252+ SpA Choice Specs Regieleki Hyper Beam vs. 0 HP / 4 SpD Kangaskhan: 268-316 (76.3 - 90%) -- guaranteed 2HKO

252+ Atk Kangaskhan Fake Out vs. 0 HP / 4 Def Regieleki: 100-118 (33.2 - 39.2%) -- 99.8% chance to 3HKO
252+ Atk Kangaskhan Sucker Punch vs. 0 HP / 4 Def Regieleki: 117-138 (38.8 - 45.8%) -- guaranteed 3HKO
252+ Atk Kangaskhan Body Slam vs. 0 HP / 4 Def Regieleki: 211-250 (70 - 83%) -- guaranteed 2HKO

The plan with Khan is to Fake Out Regi and then Protect to check him for what he does next. If he is within Sucker Punch range then kill him, it'll free your switches and relieves dangerous Volt Switch pressure

If he Hyper Beams you will Body Slam and swap to Gengar if Regi is Specs, if not then go Tangela

Gengar
You die to any Electric move lol
If he packs Swift, and he really shouldn't, then it's the same Protect scouting strat as Skewda. You can use this turn to get in Gengar and attack/sub for free. Great stuff

252 SpA Life Orb Gengar Giga Drain vs. 0 HP / 0 SpD Regieleki: 185-218 (61.4 - 72.4%) -- guaranteed 2HKO
252 SpA Life Orb Gengar Sludge Bomb vs. 0 HP / 0 SpD Regieleki: 331-391 (109.9 - 129.9%) -- guaranteed OHKO
252 SpA Life Orb Gengar Shadow Ball vs. 0 HP / 0 SpD Regieleki: 296-348 (98.3 - 115.6%) -- 87.5% chance to OHKO

You can Giga Drain if his health is low and you have a sub up. That'll let you steal some important HP for Gengar, you'll get back 35-41% of your health. Great stuff, really

Magearna
252+ SpA Choice Specs Transistor Regieleki Thunder vs. 248 HP / 248+ SpD Assault Vest Magearna: 162-192 (44.6 - 52.8%) -- 24.6% chance to 2HKO
252+ SpA Choice Specs Transistor Regieleki Volt Switch vs. 248 HP / 248+ SpD Assault Vest Magearna: 103-123 (28.3 - 33.8%) -- 0.6% chance to 3HKO
252+ SpA Choice Specs Transistor Regieleki Thunderbolt vs. 248 HP / 248+ SpD Assault Vest Magearna: 133-157 (36.6 - 43.2%) -- guaranteed 3HKO
252+ SpA Choice Specs Regieleki Hyper Beam vs. 248 HP / 248+ SpD Assault Vest Magearna: 49-58 (13.4 - 15.9%) -- possible 7HKO

Swift does 5% lol. This is another reason why he shouldn't bring Swift, it's a cope for Excadrill who we're not even bringing. This is a free switch to Gengar again for to make the of maximum results, comrade

Noivern
252+ SpA Choice Specs Transistor Regieleki Thunder vs. 28 HP / 0 SpD Noivern: 444-523 (139.6 - 164.4%) -- guaranteed OHKO
252+ SpA Choice Specs Transistor Regieleki Volt Switch vs. 28 HP / 0 SpD Noivern: 283-334 (88.9 - 105%) -- 31.3% chance to OHKO

252+ SpA Choice Specs Regieleki Swift vs. 28 HP / 0 SpD Noivern: 108-128 (33.9 - 40.2%) -- guaranteed 3HKO
252+ SpA Choice Specs Regieleki Hyper Beam vs. 28 HP / 0 SpD Noivern: 270-318 (84.9 - 100%) -- 6.3% chance to OHKO

252 SpA Noivern Hurricane vs. 0 HP / 0 SpD Regieleki: 127-150 (42.1 - 49.8%) -- guaranteed 3HKO
252 SpA Noivern Draco Meteor vs. 0 HP / 0 SpD Regieleki: 301-355 (100 - 117.9%) -- guaranteed OHKO
0- Atk Noivern U-turn vs. 0 HP / 4 Def Regieleki: 58-69 (19.2 - 22.9%) -- possible 5HKO

Noivern can't do shit vs him except Protect to scout him
Tangela
252+ SpA Choice Specs Transistor Regieleki Thunder vs. 252 HP / 248+ SpD Eviolite Tangela: 149-176 (44.6 - 52.6%) -- 23.4% chance to 2HKO
252+ SpA Choice Specs Transistor Regieleki Volt Switch vs. 252 HP / 248+ SpD Eviolite Tangela: 95-112 (28.4 - 33.5%) -- 0.2% chance to 3HKO
252+ SpA Choice Specs Transistor Regieleki Thunderbolt vs. 252 HP / 248+ SpD Eviolite Tangela: 123-144 (36.8 - 43.1%) -- guaranteed 3HKO
252+ SpA Choice Specs Regieleki Swift vs. 252 HP / 248+ SpD Eviolite Tangela: 73-86 (21.8 - 25.7%) -- 1.6% chance to 4HKO
252+ SpA Choice Specs Regieleki Hyper Beam vs. 252 HP / 248+ SpD Eviolite Tangela: 181-214 (54.1 - 64%) -- guaranteed 2HKO

0 SpA Tangela Giga Drain vs. 0 HP / 0 SpD Regieleki: 141-166 (46.8 - 55.1%) -- 69.5% chance to 2HKO
0 Atk Tangela Knock Off (97.5 BP) vs. 0 HP / 4 Def Regieleki: 74-88 (24.5 - 29.2%) -- 99.9% chance to 4HKO

Tangela can Giga Drain him to keep up on Regi's damage. Again, if he has Drampa then Knock Off and if he has Moltres and/or Drampa then Toxic. Tangela can swap into this beast but be careful, watch your HP
If he Hyper Beams then you're gonna wanna Giga Drain then swap out to Gengar
