I don't see anything wrong with that sentence, meow.

Yeah, if that happens

In this case, the word ``yeah'' is an interject that's offset by the comma.

if that happens, only the dumbest of the dummy cats will fall for it

This part joins a dependant clause with a complete one. Commas are also used to delineate if-and statements, meow.

for it, and nothing of value will have been lost.

A comma can be used in front of a conjunction to join two complete sentences. I'm not a grammar export, though; I'm just a dummy cat, meow.
