First, I'm going to determine my creature 2 drops since that's one of the most important slots in drafting, from then I'm choosing which 3drops will make the cut (another important slot), then 1drops et cetera
Woooow that's a nice very "scientific" way to do cube-building, probably it's a trivial thing but I have never thought of it that way. Now I feel the urge to build a cube from scratch with this strategy ahah.
Btw, of these 2-drops I have drafted only DMU, WOE and STX so my opinions on those:
Benalish Faithbonder is kinda meh, the enlist ability to me always felt like an almost-miss since the thing you
really want it to work with (tapping creatures with summoning sickness) is prohibited as a special case from the rules. This is a bit a feel-bad. The faithbonder, in addition, has the additional feel-bad experience that she has vigilance, but the enlisted creature still gets tapped, so... it's another thing that works a bit counterintuitively. But maybe this is all because I don't like enlist as a mechanic.
Ratcatcher Trainee is a great great great card but... I wouldn't really consider it as a 2-drop. In the sense, that I would almost never want to cast it on turn 2, the best play pattern with this is: turn 3 adventure (maybe in eot or even better as a surprise block), and then t4 double spell with the trainee + another 2-drop (a real one). You can surely cast it on turn 2 if you have no other option, but it is steel some lost value...
Bayou Groff, again, not exactly a turn 2 card, like, okay there will be situations in which you curve out (in STX draft the "dream" –with common cards– was
Unwilling Ingredient into bayou groff), but most of the times you want to wait to have something almost-worthless to sacrifice before playing the groff. Obviously, it all depends on how many disposable 1-drops you add to the cube. I still like it a lot as a card, and when I see it in a pack I always look for crazy ways to make it pop off. (I even played a witherbloom pest tokens lifegain pauper deck with 4 bayou groffs for some time)
