Endless flickering with Naru Meha?
The steps are legal.  The only thing you need to remember is to let Supernatural Stamina resolve in step 2 before proceeding to step 3 (otherwise Naru Meha won't come back).  Also, when you get to step 6 and are repeating the loop, you need to go back to step 4 and use the targets there, not step 3.  Also note that in a tournament setting you would need to explicitly state where you are retaining priority to cast multiple things in a row.
