Read my edit dude. I made a major oversight. I somehow thought he was asking if Roobushin could OHKO with a +1 Mach Punch.Way to strawman the question. Look at my last post, that is what he meant.
Anyway, the whole situation is irrelevant if Roobushin is already at +1 when Garchomp comes in; it likely won't be able to SD and Outrage.
lol 2HKOing ScarfChomp as it tries to revenge is funny. I guess I was wrong about Mach Punch's utility. That's impressive.
SubPunch still owns, though.
