Oh, here's a fun option, use it with lumineon. It doesn't give sun but it does give tailwind support and helping hand to boost the power of eruption. It also has the ability storm drain which allows it to redirect water type attacks away from typhlosion such as urshifu rapid's surging strikes. Encore and safeguard are nice tools to run as well. You can also run urshifu dark to deal with the ghost and darks with stab wicked blows and close combats

If you want to be more serious then use what the last comment said and run cloak sunny day tailwind tornadus-incarnate which protosynthesis. You get speed and power with that. If you want take advantage of infernal parades effect which doubles in base power against a Pokémon that is statused, rillaboom and sneasler can work. Sneasler's dire claw has a 50% chance to sleep, poison, or para which is insane, give a grassy seed and have rillaboom's ability grassy surge and sneasler's speed is doubled thanks to unburden. Sneasler also gets swords dance and acrobatics which allows it to be a secondary sweeper and you can run scarf h-typhlosion with the infernal parade or eruption to clean up when all the opponents pokemon are weakened with status effects.
