I'll let the math experts give you the calculations on why you
shouldn't hold only the deuces every single time.
My explanation for what you observed is that on any given day you can
probably see any crazy event in VP that you might imagine. But, if you
are interested in anything but the very shortest term, then you must
play each hand to its optimal expected return.
The comment about "it's just not giving me deuces to work with
anymore" is contrary to how the machines actually work. The
probability of deuces on the next hand is the same as the previous
hand and all others.
Or maybe you just work for the casinos and want players to lose more
overall. I've often wondered if "bad advice" on this site is intended
to do just that.
