This is Battle Spot singles by the way. My team: Jolteon Talonflame Ryperior Gallade (Mega) Greninja Swellow
Change Rhyperior to Landorus-Therian and Talonflame to Heatran. Conversely, use Aegislash. Literally any good Steel type will work or anything bulky enough with Intimidate, like Arcanine. Rotom-Heat is the old VGC 14 Mawile stopper. Be creative and use a type chart.
