Rune is the worst craft to go against because you know that at literally any point of the game they can play Dimension Climb and win by pulling a whole another turn and hand out of their literal asses and that's the opposite of fun. There's no counterplay, there's no strategy, it's literally just gambling and thinking "WOW I SURE HOPE HE DOESN'T PLAY SHIFT THIS TURN OR ELSE IM FINISHED" because you're both at the mercy of the card draw RNG.

With every other craft, you can predict or have an idea of what they might do next turn but it's impossible to tell if the enemy rune bricked or is about to pull some OTK combo out of their asses then proceed to gloat about it.
