I started using Faust the same way, as a filler before I got my full rig setup.
But there there came a game where I had Yog in hand, but never bothered to install it, because using Faust was much quicker and easier. Hell, I may have trashed Yog to break a codegate subroutine.
Eventually I realized I only installed corroder to break Wraparound, but against decks likely to run wraparound, I could probably just afford to use D4v1d to break instead, so then Corroder was out. I had 1x Mimic, but that was mostly because I wanted something for Architect. I had a CC and parasite for dealing with Swordsman.
Of course, I thought using Noise’s ID to accelerate the game is what made it work. Turns out using cutlery to destroy all the ICE works too.
