There's still Victini, he can fire off insanely powerful V-Create when banded, and has access to Bolt Strike, Zen Headbutt and momentum-gaining U-Turn.
Arcanine ought to use Choice Band as well for maximizing the damage output; as one who was extremely fond of Arcanine in the past, with my experience, the doge's best set is the offensive band.
Your Charizard X set is not the best, completely walled by Heatran. Pack Earthquake with you since a Pokemon that's weak against hazards ought not to spin them away.
Finally, Infernape is not that restrictive. You ought to note it can use Thunder Punch and Stone Edge, and to an extent, Fake Out without scarf.
