This also directly solves many of the issues that 3 candies did, so probably should just always double candy Hawlucha and take the better Reflection Cave encounters + L28 for Heracross + L30 for Meowstic.


Strat differences

Pickup Metronome.
Equip Metronome onto Lapras in Badlands menu where you turn off Exp. Share.
Move Metronome over Black Belt in Repel/Shadow Claw teach menu.
Valerie:
	Mawile: Swords Dance x2
	If 0 Iron Defense: Shadow Claw (13/16 OHKO)
	If 1 Iron Defense: Shadow Claw
		If Iron Defense after SC: Swords Dance, Low Sweep
		Otherwise: Shadow Claw
	If 2 Iron Defense: Swords Dance, Low Sweep x2 (252/256 if ID on SD turn)
Mr. Mime: Shadow Claw
	Sylveon: Shadow Claw
		10/16 OHKO if +4 & 2 Metronomes
		Dazzling Gleam does 66 / (67), Quick Attack does 8 / (9)
		→ Teach Aura Sphere over Low Sweep (Slot 1)

Always menu after Pokeball Factory instead of before (you should rarely need to heal after Valerie)

Route 15 Menu:
	- Max Repel.
	- Move Black Belt over Metronome.
	- Rare Candy x1 to L44.
	- Use 3 Proteins.
	- Heal to full.

6/16 -> 8/16 for Manectric Aura Sphere

Move Metronome over Black Belt in Escape Rope menu.

Anistar Rival:
	Meowstic: Swords Dance (+ heal if no Steadfast and die to Discharge) Shadow Claw 	Psychic 61/(63)
	Delphox: Shadow Claw
	Jolteon: Shadow Claw 		Quick Attack can do 7 / (8), Discharge 64
	Absol: Aura Sphere			Quick Attack can do 14

Do not candy after Anistar Rival.

Exeggutor guaranteed 2HKO with SC x2

In the fly menu after Olympia,
	- Rare Candy to L48 from the restore menu.
	- Move Lucarionite onto Lucario.
	- Fly to central Lumiose.

After Lysandre 1, swap Metronome over Lucarionite 
	- This equip is like 1 second slower on average when not already menuing, but I feel the consistency is worth it

Move Lucarionite back over Metronome some time before Xerosic (likely before Mable)

Game exact same as before after this
