Assault Vest can be changed to Choice Band and add the SpD to Atk instead, if it now beats something it lost to before & will be next to it. If it loses to something it beat before ^ will be next to it.
All the EV’s are for this:
Survives EQ from life orb Garchomp (ice punch 62.5% ohko) (& 100% chance to ohko)
Survives EQ from adamant Lando-T (life orb jolly 43.8% chance for EQ to ohko)
Survives Earth Power with life orb from Lando
Adamant Zygarde with 164 atk 2 hit ko’s (loses ice punch does a max of 90% with no hp or def, and after power construct Bullet Punch won’t kill) (& haven’t tested it, but with the calc it should win as long as ice punch does get a low roll)
Beats max hp max def zygarde IF ice punch does less than 54% (leftover recovery to stop power construct)
If they are Impish nature with 252 hp, anything less than 96 def gives zygarde a near 100% chance to win after 3 thousand waves. The only way to win is if you Meteor Mash turn one, don’t miss, get atk boosted, then ice punch. If this is done against max hp and def zygarde the chances of winning are much lower (% should win but need to do a better calc and in game test)
Survives EQ and Flare Blitz from Scarf Darm-g (Meteor Mash 100% ohko against 180 def
Darm-g, adamant Darm-g with Scarf has 43.8% chance to ohko with Flare Blitz) (& just click Bullet Punch, it has a 62.5% chance to ohko and you won’t have the chance of missing)
Heatran Overheat modest nature has 18.8% to ohko (life orb 100% chance to ohko) (^ loses)
Loses to Banded Rillaboom (High Horsepower 2 hit ko, Knock Off 2 hit ko)
Loses to life orb Rillaboom (Hh 2 hit ko, Knock Off 2 hit ko)
Loses to Leech Seed stall Rillaboom
Beats Banded modest Regidrago (ice punch 2 hit ko if no hp/def investment, if max hp 59% to 2 hit ko)
Beats AV Regidrago (2 ice punches + bullet punch)
Survives Thunder from Specs modest Regieleki (& thunderbolt has a 43.8% chance to ohko)
Survives Shadow Ball from Specs modest Gengar (^ loses)
2 Bullet Punch’s 9.8% chance to ko scarf togekiss, bullet punch takes 4 hits ko max def and max hp. (& Bullet Punch 2 hit ko’s Scarf, 35.2% chance to 2 hit ko max hp and max def)
Beats Sylveon
Loses to Iron Defense Leftovers Tapu Fini with Scald (252 Hp, 150 def. Would need 2 crits with no burn to ko)
If they have leftovers Iron Defense, Calm Mind and Draining Kiss you lose (same stats)
If They have Iron Defense, Draining Kiss, leftovers, but no calm mind (You can win if you get attack boosts
https://replay.pokemonshowdown.com/gen81v1-1406299092 , but if you don’t get any boosts you lose. If they don’t have an attacking move besides Draining Kiss and they don’t have any other moves healing you should win as long as you get +1 atk when they run out of Draining Kiss and you run out of Meteor Mash so you deal ~4% every turn with EQ (they must be below 64% to win, or you need a crit))
Against Scarf Fini you should live 3 Hydro Pumps if they are Timid Nature (Meteor Mash does ~48-54% so all you need is 2 Meteor Mash’s and a Bullet Punch possibly to win)
If Scarf Fini has Scald the only way it wins is if it burns turn 1, or if Meteor Mash misses 3 times (& should beat all Tapu Fini’s, but need to do in game tests)
Beats Specs Tapu Koko after EQ then Bullet Punch (Thunderbolt has a 1.2% chance to 2 hit ko Timid Nature)
If Tapu Koko is Electric seed then EQ does 48-56% if they are max hp (Thunderbolt is 31.1% chance to 4 hit ko if they are max speed) (&)
If they are seed with max hp max def EQ does 33-40%. I(f they roost use Meteor Mash to try and get an attack boost) (& EQ does 58-68%)
Beats Specs modest Kyurem (Earth Power does 70% max, Meteor Mash doesn’t ohko so you need to click Bullet Punch after to ko) (^ Earth Power has a 81.3% chance to ohko)
Loses to Whimsicott (& Meteor Mash ohko’s)
29% chance of beating Specs Primarina (Missing Hydro Pump once and hitting both Meteor Mash’s (also need to use Bullet Punch afterward) (& 18.8% chance for Hydro Pump to ohko, if the are faster than you, you lose unless they miss Hydro Pump)
81% chance to beat Hydrocannon (90% chance to hit each Meteor Mash) (^ loses to Hydrocannon)
Against max hp custap Primarina if two Meteor Mash’s do under 75% you win if you hit the third (if they are slower then you). If you do 80% (max amount) after 2 Sparkling Aria and custap berry Hydrocannon then you lose (unless they miss, 10% chance) (^ you lose if they have Hydrocannon)
Beats Blissey
Loses to Specs Volcanion (If they aren’t specs and have no speed investment then whoever wins is a speed tie)
Loses to Venusaur (& Ice Punch should win against max hp unless they have a decent amount of def investment)
Loses to both Urshifu’s (& Zen Headbutt Beats Rapid Strike)
Small chance to beat life orb Bisharp (Knock Off has 25% chance to ohko, and you would need a high roll on EQ so Bullet Punch would kill) (& Wins unless they have band)
Beats Specs Naganadel (Fire Blast does 77% max, EQ has 81% chance to ohko, if it doesn’t ohko click Bullet Punch) (^ Loses)
Most Likely Loses to Durant (double Superpower has a 12.5% chance to 2 hit ko, to ko you would need a high roll on both EQ’s so that Bullet Punch kills) (% Should Win)
Probably loses to registeel (& Wins if they are max life and SpD not def)
