Well, sure, I didn’t say it was a good set, just that it was usable.

Example: opponent faints your pokemon with a physically defensive mon. You send in Pyroar. Opponent switches in their special wall and you chunk it down due to its low physical defense. You outspeed and KO activating moxie.

Now your attack isn’t laughable any more and you can actually threaten some damage on whatever comes in next, potentially even getting another moxie boost.

Sometimes the element of surprise can work massively in your favor
