Is training with Macho Brace worth it?

Question

I know it makes it easier to EV train but doesn't it make the Speed Stat lower?

Answer 1

Yes it makes the speed stat lower but it is worth it, it makes EV training so much easier. I use it all the time. If you have the BP you can also get Power-items that can make it even faster!(They still lower speed though). Though remember the speed is only cut in half while it is the hold item, it does not permanently cut the speed or anything, you can even use it to EV train speed XD. Have fun EV training.

Answer 2

It depends really, if your Pokemon really relies on speed to win a battle, then I would say it's not worth it. But a Macho Brace only lowers speed in a battle, so if your Pokemon has other ways to win a battle without speed, Go For It!
