OK! Well I saw that there was no sub heatran set in the analysis, and since it is really one of the better sets it seemed like a good idea to have it added! This is the first Analysis I have done, so I'm not totally sure about conventions. Also I hope it isn't a problem that I wrote quite a bit for this set.

[SET COMMENTS]
<p>The idea behind this set is twofold: first of all, Heatran is one of the best in the game at forcing switches, due to his nearly universal coverage, great typing, and frequent use of Choice Scarf, so it is not difficult to get a Substitute up. Second, the only Pokemon that are immune to Toxic are Steel-types — easily taken out by Fire Blast and Earth Power — and Poison-types, all of which have either poor special defense or a Fire or Ground weakness.</p>
<p>Heatran should be sent out against something that will likely switch out, such as a Celebi or one of the many Steel types in OU. In consideration of this goal, it is often useful to send Heatran out for the first time after one of your own pokemon has been KO'd; most players will assume it is holding a Choice Scarf and switch out of the expected speedy attack. Once you have a Substitute up, make your play according to what they switch to. If they for some reason switch in something weak to Fire or Ground then you will attack it, obviously. If they don't, then you are still OK, since most of Heatran's common switch-ins—things like Gyarados, Tyranitar, Salamence, Swampert, and the bulky Water-types—absolutely hate being poisoned. Once you Toxic them and they break your Substitute, you can switch to something to stall out their attacks, and the next time you bring in Heatran your opponent will have at least one fewer counter for it!</p>
<p>Toxic is recommended because it has the greatest coverage of all the options in the last slot, but it isn't that spectacular without a reasonably bulky team to take hits from pokemon after they have been poisoned. For this reason several other more specialized options are available if you are running a more offensive team. Explosion is an all-around useful move, carrying the ability to take out Blissey and pretty much anything else your team has trouble with. One of the cool things with Explosion is that almost no one will think to switch to a Ghost if you explode with a Substitute up, which just makes it all the more useful (note that a Naive nature should be used with Explosion). A certain Hidden Power can also be selected if you want to be able to quickly take out any one of either Gyarados, Salamence, or Swampert instead of slowly waiting for Toxic to do the job. Finally, Will-O-Wisp is possibly more useful than Toxic against Gyarados, Salamence, Tyranitar, and some others, but it kills even slower than Toxic (and can even be circumvented via Recover or Roost), and the 75% accuracy is a pretty big turn off.</p>
<p>It may seem strange to use a +Speed nature without a Choice Scarf, but in a metagame where Heatran is as popular as it is, max speed can be a huge aid. With full Speed, Heatran will attack before +Speed Breloom and Metagross, and before neutral speed Gyarados, Dragonite, and Heracross; and it will nearly always outspeed the defensive base 100 Speed Pokemon. Any of these could easily OHKO or status Heatran, so getting the jump on them with Substitute or Toxic is often crucial to the outcome of a match.</p>
