Hey man, nice work here, there are however some parts that I would like to comment 'em.
You just said that hawlucha can use swords dance on predicted switch , well okay, but isn't the thing too much "general" so to say? What if the opponents brings a faster threat like I don't know, Thundurus? Wouldn't that made the momentum you had the turn before useless? I would say it is better to remove this part on "usage tips" remember, newcomers mostly read analysis, it's better to be specific, you can't just use swords dance on Hawlucha any times you have a positive momentum in a battle.
While pursuit is surely a great deal on this pokemon, choice scarf tyranitar isn't really the best teammate to it, not only do they share a fairy weakness, 'tar is locked, meaning that aegislash can simply wear him down with king's shield and sacred sword, on the other hand, assault vest bisharp might be a better 'mate, considering that sucker punch won't be affected by aegi signature move, our favorite robot (is it? lol) is also a splendid check to Latias, and Latios, frankly, even better than tyranitar, considering he is part steel, of course I know that you already cited Bisharp, problem is, Bisharp is much better than scarf tyranitar for Hawlucha, making him a... lesser choice not really worth the mention.
Heatran is most surely a great teammate for Hawlucha, they cover each other quite well, but heatran cannot switch so easily against aegislash, due to sacred sword, you should point that.
Same for Thundurus, Excadrill checks it only if he's the assault vest version, otherwise focus blast literally kills him.
And last but not least, sd+lum berry should get an OO mention, having the ability to switch, or set up on common status attacks like spore, WOW, etc, activating unburden then is invaluable, coupled with swords dance, even more.
