what is smartest, to max out chandelures speed to 284 or to minimize it to 148 and teach it trick room?
it has decent speed, but most things will outspeed it so I'm not sure...
I actually would prefer the Trick Room with minimum speed, because then you can invest some EVs in HP and Defenses, and if so, then the moveset would be:
EVs - 252 Defense/152 HP/104 Sp. Defense.
Calm Mind - This will let you have pretty good special stats.
Flamethrower - STAB, reliability.
Trick Room - Anything to say?
Energy Ball/Shadow Ball - Coverage or STAB? your decision.
