Let’s start with relic demon hunter. What is Theo stealing that’s causing the class to lose? Even if they steal Xy’mox, they can still buff up their relics and get to 2 7/7s and 2 8/8s, they also run denathrius. So theo steals denathrius instead, they can still buff up relics. Therefore, they still have win conditions even with Theo stealing cards, yet the class generally sucks. That’s because Theo isn’t what’s making them suck. I honestly don’t know what DH could use to get better, but I’m not in the market of designing cards or successful card games. Point being, relic demon hunter has numerous win conditions, no single card that getting stolen from Theo will cause them to lose the game, and yet they still lose a lot.
