Double Fire Heatran! I'm aware Leftovers is "disallowed", but this plays differently and goes off of a specific luring concept that is quite different than the normal variants. To explain, if you reveal Lava Plume in the early game with Heatran, then Toxapex is far more likely to stay in against you to go for Knock Off/Scald/Recover. From there, getting off a Magma Storm makes it very easy to trap it. The same goes for things like weakened Blissey or Clefable. While you lose the ability to set-up Stealth Rock like the normal set, which can easily be fulfilled by a number of other common options, you gain a ton of practical surprise value that can help eliminate common defensive options. Lava Plume in general is a good move as it can burn things and still does solid STAB damage, but using it + Magma Storm opens up a ton of scenarios where the opponent is lured into a false sense of being able to switch by a former only to be trapped by the combination of the ladder and Taunt+EPower. Being able to remove a Toxapex or a Clefable can open up so many potential paths for teams, too. I think this Heatran set is super underrated, but it is admittedly a little more challenging to fit onto teams than the normal sets we see that have other defined roles (although that is the case for most fun sets showcased here I reckon).
