________________________
NOTES:
Arcanine:
Speed IVs: 21, this outruns 31 IV, 4 Speed EV Blastoise
EVs: HP and SpDef calculated to take the least amount of damage from bulky rapid spin Blastoise's Scald (44.8%)
Max Attack for greatest damage output (71.1% chance to 2HKO MAX HP & MAX DEF Blastoise after Leftovers recovery.-------- guaranteed 2HKO after Stealth Rock and Leftovers recovery)
Abilities: Intimidate for more defensive utility and to patch the defensive hole left by 0 EV investment in Def.
Justified for positive interactions vs knock off spam and because of dark weak team.
______
Duraludon:
Speed IVs: 19, this outruns 31 IV, 4 Speed EV Blastoise
EVs: HP and Defense calculated to take the least amount of damage as possible from choice band flygon (62.5% chance to live Earthquake), while still being able to 1HKO it with dragon pulse. It also conveniently takes a maximum of 88% from +2 Attack Earthquake from Drapion (Barring a crit) and 2HKO's it with dragon pulse with or without black sludge and without the need of hazard support.
______
Bronzong:
IVs: 0 Speed for maximum gyro ball power.
EVs: Minimum attack required to 100% of the time 2HKO Max Speed, Max Attack Drapion. Max Defense to utilize Zong's beautiful 116 Base Def, the rest of the points go into HP to give it better chances to live anything Drapion can throw at it except a +2 Attack, Sniper Critical Hit. Unboosted Drapion Non-sniper critical Knock Off does a maximum of 50.4%, and unboosted SNIPER critical Knock Off does a maximum of 75.5%. No matter how much HP and Def you give Bronzong, it cannot live a Sniper Boosted, +2 Attack, critical hit knock off. EVER. Pray you don't get crit...
Moves: With this more defensive set, I want to hit opposing bronzong really hard and boom to get out of the way for a trick room sweeper.

______
Rapidash:
IVs: Min Speed for Trick Room + room service bringing it to 128 speed.
EVs: HP and Def calculated to take a maximum of 66.8% from choice banded Pangoro's Knock Off. The rest is pumped into Attack to make use of the high base stat + Swords Dance. Conveniently, even without Swords Dance boost, Rapidash will always 1HKO Salazzle provided it hits its Zen Headbutt.
______
Indeedee-F:
IVs: Min Speed for Trick Room
EVs: HP and SpDef high enough to only take 64.9 - 76.5% from +2 SpAttack Salazzle's Sludge Wave (without being a critical hit)
Defense and SpAttack may need to be balanced further to either live important hits or deal important damage.
