Start with only Mana Beast, when you cast it add Void Lure and start clicking voids. You won't be recasting Mana Beast again so don't put it on reckless.
Add Siphon Power and wait to have 1 charge, then fill the bar with Nullzone, Materialized Doppleganger and Fire With Fire (you will have to cast Counterspell once to get to the level needed for Fire With Fire). When you can replace Mana Beast for Counterspell.
After a minute you should have completed the challenge.
If the challenge seems to proceed slowly, clicking voids is the easiest way to speed things up.
