Machamp - Attack (Physical)

[Marcusube]

This is a good build, however I have a concern. If Machamp is so slow and relies on Trick Room, the fact that you're using an Assault Vest means that the first turn before setting up Trick Room so Machamp would be open to getting fainted by faster opponents? Sure you could make the argument that Machamp can be used late game but that really comes across as ineffective.

Also why not just invest more into attack seeing as how Machamp with a little more attack investments can OHKO opponents instead of leaving it to chance?
