As many others have probably experienced, recently I arrived at the glass factory during my play through, specifically the series of double battles. After being unable to win for quite some time, I began to look online for ways that others have won, and came across this video:
Obviously, this strategy appealed to me because it only required me to catch and EV train 3 pokemon, which I was able to do with a few hours' effort. However, I found that I was still unable to out speed some of Shelly and Cain's pokemon, specifically the Meowstic and Scolipede, despite having near perfect speed IVs and EV training that favored speed for both pokemon. The question I have is whether or not some change was made in more recent versions of the game to prevent this strategy, or if I should try to get perfect IVs, or if I would be better off just trying to beat the fights with the pokemon that I already have. If anybody has any kind of alternative strategy that I could use also, I would be open to those suggestions as well, although if anybody has a reason why the strategy in the video doesn't work with a quick fix, that would probably require the least time investment from me. Thanks for the help!
