This move set can be used effectively, and is also versatile. It makes up for Chandelure's short comings and can also screw your opponent over. It may look familiar, though...
Chandelure (M/F) @ Choice Scarf
Ability: Flash Fire
EV's: 4 HP / 252 SAtk / 252 Spd
Timid/ Modest Nature (+Spd, -Atk) OR (+SAtk, - Atk)
- Fire Blast
- Energy Ball
- Shadow Ball
Chandelure has decent defenses and stellar Special Attack, but low Speed. That combination screams Choice Scarf to me; this guy is like a Specail Darminitan.
Simple: hit hard with STAB attacks or pound cocky Rock, Ground, and/or Water types. Trick anyone who dares set up, of they survive.
*Chamdelure is immune to BOTH of Ferrothorn's weaknesses, so pairing the two is a good combination as Ferrothorn resist all of its weaknesses.
