Alright, riddle me this batman rules lawyer.

I have leyline of anticipation, hive mind, mirari on the battlefield

I cast turnabout, paying the 3.
I resolve my mirari turnabout, untapping my lands
I cast narsets reversal on turnabout, paying the 3
I cast display of power before narsets resolve
I use my copies of narset to copy/bounce their narset/turnabut
I cast sorceress schemes to retrieve display of power, letting mirari copy resolve before casting narset and turnabout again
infinite mana

Does this work?
