In the lower tiers, I could see it running an offensive set using it’s amazing typing + ability to set up. I would use 252ATK/252SPD with Shift Gear/Flare Blitz/Iron Head/ Substitute or coverage move. In OU, it’s amazing typing + ability allow it to perform as a decent check for several pokemon such as Bulky Talonflame/Garchomp/Jirachi/Metagross w/o Hammer Arm. The EV spread I would use is 252 HP/252 DEF with Lava Plume/Thunderbolt/Toxic?/not sure about the other moves yet until more tms are released. Still, I think I would use Heatran instead, but D-Vespiquen becomes an ok option due to the levitate ability.
