Tips for next step. Farming t11..

To a little over 10k waves getting about 200t coin per run. Off and on with 4x speed up. T12 i barely am getting over 6k waves and am a bit weary of attempting the dissonance runs on some of em. Many of the usual lab suspects I have gold boxed. Transitioning from full blown eHP to a bit more atk and CC. The important things..i have anc gcomp and anc being annihilator. Rest are mythic (primordial collapse & sharp fortitude). All are around lvl 156.I have the holy trinity synced at 2m CD. Do I keep incrementally decreasing CD of trinity little by little or do I dump into perma BH? Is it time to do a card mastery? From what ive read im not making enough coin to do my first card mastery. Never doing terribly well with tourney and likely to be stuck in Champ for *quite* some time at this current rate. Thank you for your help.
