Haven't read on reddit either. I think you can put the scenario in your opponent's graveyard with Vilgefortz: Renegade after setting up the practicioners and then spawn new ones.How would it help getting a scenario? Heatwave the Scenario will not put it in GY, right? Can you please explain the hypothesis? Sorry, I don't visit reddit.
Edit1: Another idea: Create as many IP's as you can with Operator, Megascope etc. then play Vilgefortz: Renegade on Joachim...
Edit2: Or Canta and play your opponent's cards for the rest of the game
