To provide another side of the argument, I run almost *every* 2 CMC or less red "draw and discard" sorcery in my deck. My list is more of an all-in storm deck, and as far as I'm concerned, there are two states your hand can be in while playing Zada--either you have a cantrip, or you don't. If you have a cantrip, you're doing great, the filter spells are just gravy on top of it. If you *don't* have a cantrip, you're falling behind and you really want to find one, so filtering and wheeling is extremely useful there. The same logic also applies if you have cantrips but no creatures.
My biggest caveat to this is that if you're not playing as-fast-as-possible storm, the filtering spells lose a good amount of value. My deck essentially never wins through combat, and runs two pump spells total, relying on mass draw to get me where I need to go, taking out my opponents before a sweeper shows up. If you're more interested in a less glass cannon-y version, or one involving more creature combat, playing more ways to kill your opponent is definitely the right call. I still like Faithless Looting and Wheel of Fortune, but otherwise I agree with the consensus here. Just wanted to point out a context where those spells do some work.
