[SET COMMENTS]
<p>Heatran is a Pokemon that can force out many different Pokemon with its high Special Attack and useful resistances, and this set aims to make use of those free turns to set up a Substitute. This lets it take down switch-ins that can outspeed and KO it, such as Terrakion and Landorus, without relying on guesswork. Substitute also makes Heatran harder to revenge kill, as Pokemon have to break its Substitute without being OHKOed by any of its attacks. Substitute along with Toxic allows Heatran to cripple common switch-ins to Heatran that would otherwise easily wall it, including Jellicent, Rotom-W, and Dragonite. Using Substitute makes the opponent take another round of Toxic damage, and after a few turns, either Fire Blast or Earth Power can 2HKO. Heatran also makes for a good Toxic user in general, as it is able to take down most Steel- and Poison-types with STAB Fire Blast or Earth Power.</p>

<p>252 Speed EVs and a Timid nature enable Heatran to outrun standard Gyarados and Dragonite and take them down with a combination of Toxic and Substitute. Maximum Special Attack makes Heatran as threatening as possible, but a bulkier spread can also work. If you decide to use such a spread, you should shift some Special Attack EVs—not Speed EVs—into HP or Special Defense, as the ability to outrun Gyarados and Dragonite and to Speed tie with other Heatran is extremely vital to this set's success. Roar can replace Toxic on Spikes-stacking teams, as the entry hazard damage can pile up quickly, but the ability to cripple common switch-ins is usually preferred. Will-O-Wisp is another option in the last slot as it halves the Attack of Dragonite and Gyarados, but Toxic is mostly superior as it can't be stalled out with Recover or Roost, as well as having superior accuracy.</p>
<p>Because two of the most common switch-ins to Heatran—Politoed and Tyranitar—are weather starters and are worn down by Toxic, this set functions excellently on sand and sun teams as it greatly helps with winning the weather war. Thanks to Substitute and its decent Speed, Heatran can easily Toxic stall both Tyranitar and Politoed, enabling your own weather starter to have complete control. Heatran also pairs well with Pokemon that appreciate bulky Water-types being poisoned, such as Dragonite. Dragon Dance Dragonite is able to set up on poisoned Water-types, while Toxic wears them down and puts them range of being KOed by Outrage or Dragon Claw. It's worth noting that there are two Water-types that don't mind Toxic, namely Starmie and Hydration Vaporeon. Therefore, a teammate that can deal with those Pokemon, such as Rotom-W or Ferrothorn, makes for an excellent choice.</p>
