The opener hasn’t really changed since last tier aside from adding in a second triple cast. Only fight I can remember doing pre pull leylines is e12s, so it lines up better with shiva/titan mechs.

Opener used to be sharp -12s, f3 -3 seconds, t3>f4>triple>f4>pot>f4>Leylines>f4>swift>despair>font>f4>despair>b3>sharp>t3>b4. Now you switch last t3 for paradox. I wouldn’t use xeno in the opener, I’d save it for mechs. Holding that xeno will give you a weave window for triple if you held it in the opener (lines up with fireplume movement in p3s and disease/tether swapping in p4s)
