>>56370320I replayed Emerald's BF so many times, I can just list things on how to beat them.
>FactoryAt the beginning is easy, but you may start thinking around the 4th or 5th run. I had an interesting surprise when I got an Umbreon with Double Team, Sand Attack, Faint Attack and Baton Pass. I pass into an Altaria with Dragon Dance. Easiest run ever.
But anyway: Ground, Ice, Dragon. That should cover you.
>DomeWhile you need 3, I recommed quicksaving before entering the fight. There's a random chance you get to fight against 2 easy picks, so you better exploit that. Some set ups can work against the IA itself, so get good mons, and abuse the RNG.
>ArenaBest of 3. If you damage enough, or just 1 hit if possible, it shouldn't be much, only endure. Be aware of Endure + Salac Berry + Reversal users. And bring a Flying/Fire type for Greta. Don't let Shedinja catch you unprepared.
>PyramidLOOT at the beginning. The first runs are loaded with healing items. After that, only hold items, and you will need all the status, PP and HP healers you can get. Maybe invest on a Blissey and a Miltank. Remember: only 10 items max.
>PalaceNatures are dumb. I admit I just abuse the savestate function and push through. Be aware that if your Pokémon fails to power up in one turn, THAT turn will be 100% a failure. Is better to save BEFORE even entering. Is like the fights are scripted on when it hits and when it misses.
>PykeGet a really fast mon, and savestate before going into any choice. If you are lucky, you should get an "empty" road. With enough Spd, you can outrun most encounters. You can also get a fight with a maid that will heal your stats, or just a room where a dude says a random thing. Avoid the status rooms, they will either hit your lead or both of your bench Pokémon.
>TowerThe same as Dome, but this time AVOID Endure + Salac + Reversal. Be also aware that many enemies will have 1HKO moves after the 5th run.
