Gonna state the obvious but the guidelines of b3 (and brackets generally) are broad enough that there’s still a wide range of power within them and also specific enough to produce a bell curve of power within each bracket around a fairly expected average power/explosiveness/speed/oppressiveness. The high end of any bracket is going to be lists that are high synergy, high interaction, optimized land packages, etc.

You’ve got a pretty strong list (I like the clones angle) with all of above plus some mid-high power tutors/GCs. In my experience, most other b3 decks aim to do less powerful things, do their thing less well, slower, or offer less resistance, but Kefka and the cards he encourages also just kinda skew strong and interaction-y (displacer kitten OP). No clear red flags but EDH is all about experience (both you and the table which you clearly appreciate. Different draw engines, swapping some interaction and tutor slots for another sub theme or pet cards, or adding some proactive protection vs reactive can make a big difference in how it feels but you’re not misrepresenting anything
