Some inspiration, please?

So I've been in a slump as to what pokemon I should make next.
I want something original, and not used much (Regardless of tier. Example: Dragonite is almost never used anymore since Mence)

For Fighting pokes, I barely see Hariyama. I mostly see Lucario, MAchamp, or Breloom. So Hariyama maybe?

Already have two hariyamas =/

So, I have an idea for a mixed Arcanine, but I'm having a horrid time with the nature and spread

Moves:
Reversal
Substitute
Fire Blast
ExSpeed/TFang/HP Grass

Item:
Liechi/Salac Berry

Nature:
Naive/Hasty

Ability:
Intimidate

Current spread

200Attack/56SpAttack/252Speed

Max speed at 317, Attack is 306, relatively low, so Liechi berry is preferred, 275 SpAttack

IVs:
HP 30
Attack 31
Defense 29
SpAttack 31
SpDef 28
Speed 31

The tactic is to force a switch with Intimidate to get a free sub up, then to Fire Blast until you can sub up for the berry, and then commence to take out anything weak to fighting with Reversal, and ExSpeed to finish off a sash'd foe that's broken your sub, or to deal a bit of damage before you get KO'd

On shoddy, it worked REALLY well with an Ingrain BPasser to get more HP for a sub, but even with this, Flare Blitz would be out of the question, draining the HP too fast


The only other option is
Reversal
Substitute
Flare Blitz
Morning Sun

What's everyone's thoughts?
