I ran a deck on the test server with 3 Voltars ring and 3 portal. Did alright, but you can't really fit in the usual human rush (in particular Kris). Rating was around 250 with it there at the end (290-300 initially when everyone was experimenting more)

You don't NEED to set up the ring mind, often portal T4 then normal nishaven is enough. Against shadow heroes due to gargoyle and MA you are more likely to want the ring in place early. Against Zaladar/Elementalis the ring is very important to get in place early.

Draw is a difficult question for the deck mind. T4- portal? TO? Ring? Heirloom?
