A few alternatives are Chandelure and Rotom H. Swap T-tar's moveset around and make Chandelure Anti-lead with Acid Armor/WoW/Pain Split/STAB Move, although I don't know the EV spread we'd use, and it would probably be Timid with Flame Body or something. Rotom H could have Hex/Overheat/WoW/X, although that's only an option if forms can be used over Wifi without an AR code.
