im well aware some of these are incompatible simply because the combined behavior is hard to implement.
most of these would benefit very few, but some of those would be very easy to fix.
hard rock and mirror (yeah i know "the Hard Rock mod flips the beatmap on it's X-axis", that doesn't mean they should be incompatible),
sudden death and target practice, hidden and (spin in, traceable, depth), flashlight and (blinds, bloom), relax and magnetized,
transform and (wiggle, magnetized, repel, freeze frame, depth), wiggle and (magnetized, repel, depth),
spin in and (grow, deflate, depth), spin in and (grow, deflate, depth), traceable and depth, barrel roll and bubbles,
approach different and freezeframe, noscope and bloom, magnetized and bubbles, repel and bubbles
