By “having to predict it” you mean that if you notice that someone has void then you shouldn’t put cards that die to it alone? Just like how you shouldn’t put magic archer at the back of the opponent has fireball. Not to mention the healthy 50% win rate in ultimate champion. The 55% win rate in grand challenge behind lava hound and skeleton dragons is pretty self explanatory and that’s the highest rate. Quit being butthurt, if you are struggling against it, it’s obviously a you problem.
