MEGA LATIOS DRAGMAG

Teambuilding process:

I felt like the best way to abuse Magnezone with a dragon might be with specs pult + Body Press magnezone, as a lot of teams are relying on Kingambit to deal with pult. I went for Specs Pult specifically over Dragon Dance, because I often felt like DD can be inconsistent at times (the Z-Move set in particular), and sometimes prone to be played around, while Specs Pult is pretty much a good wallbreaker at almost any point of the game. Magnezone's EVs are to outspeed max speed ada kingambit, while the rest is put in bulk and physdef to make it as good as possible into Kingambit. Toxic targets the very dangerous Volcarona so you are not setup fodder for it (shoutouts
peap for the idea), while hp fire+tbolt target the other steels.

As I was going to build a team with 3 dragons, I went from the assumption that I wanted to be as safe as possible against Dragapult, so Kingambit felt like a natural addition. On top of that, it provides an other steel and is able to attempt to pursuit a choice locked Tapu Lele (Which is the motivation behind max hp). I eventually decided it to be the rocker - though this is something you could probably slot on Kommo-O too. The tera can probably be dark instead of ghost, which is here just to be a lil bit more annoying to fighters, even though you don't do much back to some of them.

With a Magnezone and a Kingambit, the stars seemed to align for Mega-Latios, which was already known to appreciate magnet pull and pursuit support in gen8 (See
this post from the gen8 VR thread), which I believe is still true right now with the existence of Dragapult and Gholdengo. I went for a substitute set, which allows it to take advantage of a multitude of defensive presences while pranking Heatran, which is one of the few steels Magnezone cannot trap.
Honestly I'd like to give a special mention to this mon, because from testing it seemed really incredible, especially against the myriad of sun teams populating the ladder right now, which it
utterly reduces into pieces, and often are forced to attempt to revenge kill it by locking Walking Wake into Draco Meteor, leaving it easily trapped by Kingambit. This pokemon in general is a nightmare for a lot of builds right now, and it definitively deserve more recognition.

Volcarona is pretty much forced here, as I needed a strong iron valiant answer, on top of an alternative win condition which can carry the team through difficult matchups, especially against teams including multiple fairies. I went for flamethrower modest, but timid and/or Fire Blast are probably valid options here as well.

An other win condition, being the third dragon slot, which also provide an additional Kingambit check (never too safe against that mon lol), and an important threat to rain teams, which otherwise can be annoying to this team. It also can be useful to grab informations on SpA Wake and Tapu Lele sets, in terms of speed tiers (scarf vs non scarf)
Additional thoughts about Dragmag as a playstyle
I think it is interesting to note how different the team is from BW dragmags, in terms of gameplan: obviously, the "trap steels into spamming dragon moves" gameplan doesn't work anymore due to the existence of fairy types, so I felt like you had to take an other approach than the bw dragmags. Only two of the three dragons in this team use dragon moves, and one of them (Kommo-O) doesn't really care about Magnezone's support anyway. However, the Dragapult vs Kingambit dynamic itself is, in my opinion, more than enough to justify a magnezone structure, even though Dragapult is more likely to click Shadow Ball rather than Draco Meteor once Kingambit has been taken care of. To be honest, this team is more a magnezone team with three pokemon that happen to be dragon types rather than an actual dragmag team, and this is just symptomatic of the fact that spamming dragon moves is not a consistent gameplan in a fairy types infested metagame.
