Just had a lot of fun playing my mage deck, I'm hovering in rank 14 but seem to win a lot of games there with this deck (was also playing priest but that deck needs work), and that deck doesn't even have pyroblast. Pyro is definitely a pain in the ass but again, I'm not so sure mage is OP, they're just really frustrating to play against because there's no defense. It'd be interesting if there were some ways to counter spells (other than mage secrets)
Had an awesome game against a pally. Kept him controlled for the early game by hitting him with water elemental to keep that bloody truesilver off me, but he had a card and health advantage by midgame. We went into very end-game with me having half his health, he ran out of cards first, and would've won, if my final cards weren't Antonidas one turn, then next turn magic missiles into two fireballs from the archmage. Good fun. I had 1 health left at the end, neither of us had any cards, closest finish I've ever had.
