Jace and Rings of Brighthearth

[serracollector]

If you copy the BrainStorm ability with brighthearth, is it draw 3, 2 back, then draw 3, 2 back, or is it draw 3, draw, 3, put 2 back, put 2 back?
Also, can I pop a fetch in between?  Like jace, draw 3 put 2 back, pop fetch, shuffle, then copy, or somehow put the copy stacked on the fetch etc?

It's draw 3, put back 2, repeat...

You can pop a fetch in between...
