A team for every battle facility might take a very long time.
Are we allowed to make a team for each facility on each answer?

Yeah, you can have one team per answer but if you feel like it you can have, like, 3 Trainer Hill teams on this one question, provided that they are on different answers. You also do not have to answer for every singe facility.

Basically, yes :)

There's no Trainer Tower in Emerald.

oops thanks

Hello everyone, I already obtained the gold symbols years ago so I'd like to share my experience, starting with the Battle Tower. I don't remember my team's IV distribution well, I don't know RNG manipulation so I made sure everyone had 20-ish ivs in all stats. And since there's no way to check evs, the distribution is kinda iffy (just look at Metagross...). And at the time I liked relying on hax-items which helped in some ocassions but I don't recommend it now unless you are hard pressed by the item clause.

Basically, my strategy was to lead with Heracross and go all out offensive, her weaknesses being covered by Metagross and Starmie. No set up sweepers or anything fancy, just a lot of physical and special coverage and a exploding Metagross if things started to go wrong.

Against Gold Anabel, my Heracross took a +1 Tbolt and 2HKO Raikou with EQ and Brick Break (in case she went for Reflect, which is why I didn't want Choice Heracross here). Then to my surprise my Heracross outsped and hit her Brightpowder Latios, now I know that those Frontier Lati twins have no speed investment lol. Hera went down to Snorlax after dealing a chunk with Brick Break, so Metagross went BOOM and finished the job.

The main reason why I chose this team instead of the many better teams on Smogon is that Heracross, Metagross, and Starmie are all on the Hoenn Pokedex. This means you can build this team using one copy of Emerald and no other games.

There is a rule that explicitly prevents me from copying the team, so I moved 4 of Metagross's EVs from special defense to physical attack. This answer now does not break any rules.

Why not use the team that the famous Pokémon speedrunner Werster used for his Battle Frontier speedruns? (Swampert, Metagross and Latios)

---

This team is intended to get long streaks, while Werster's team is intended to quickly reach 70 battles and then stop. You can use whichever team you want.

---

Why Guts + Lum Berry? If you get statused to boost guts, lum berry gets rid of it.

---

It's mostly for paralysis and sleep. You can use a black belt if you want to keep the statuses.

aaaah, i see, thanks!
