A combination of Facade, Flame orb, and the ability Guts can be real handy in tough defensive situations.

Life orbs takes away HP but provide excellent attack boosts.

The ability solar power boosts special attack in sunlight but takes away HP, making flamethrower an even more powerful move even with the added fire-type-boosting power of sunlight.

Bide can do double the damage taken in three turns making it one of the most powerful moves in your arsenal.

Endeavor does double the damage in one turn.

Payback does double damage if the user is hit first.
