This is my first post so try not too judge.
White smoke - if you do not want ur stats to get lowered(lose your coil)
Flash fire - immunity + 50% atk boost if hit
Coil - better version of bulk up. Acc. can help with inferno
Inferno - for damage and mostly burn. Acc. boosted by coil + STAB. Sp. Atk still not too bad.
Fire lash - dmg + STAB + defense lowering for more damage
Not too bad for g-max centiferno.
Flare Blitz/ Burn up/ bug or grass or type move/ thunder fang /anything you like
Flare blitz- dmg + STAB
Best move that it can learn for g-max centiferno
Burn up - to reduce weakness but also reduces resistance. flash fire still blocks fire. Dmg + STAB
Bug for STAB
Grass for coverage
Thunder fang for coverage + effects
Evs I'm kinda new
I think something like:
252atk/ invest in either bulk or speed; up to u
