this utilises 5 cards - knife juggler, radiant elemental, test subject, Topsy Turvy and embalming ritual. It is important to only play these once you have all the other pieces in your hand. If possible, I would advise adding a second knife juggler just to speed the process up, as you may have to complete this combo at least 70 times otherwise (which is very tedious)
whilst getting thy is combos your hand, focus on clearing the board and healing yourself - don’t bother attempting to put pressure on and hit Reno’s face, as you will be able to do all that damage with your combo.
