And CMC3 is more awkward for them to try and Counterbalance. I can see cutting one, but I'd rather have one than the fourth discard spell for sure.

I've actually started to cut Force of Wills instead, since they have a much smaller number of must-counter threats now that some don't run Entreat at all.
It's probably more correct to bring in NoSB (if you play that card) over any deluges. NoSB can be played proactively, and deals with all snappys, cliques and mentors at once. I wouldn't cut forces even if some lists plays 1 instead of 2 entreats, there are still plenty of cards that might require a force.
