It was a Tempo Mage, they do not play Pyroblasts or Forgotten Torches(only Freeze plays Pyro and only Reno and some Freeze play Torch) and he had already played Ethereal Arcanist and used the spell. He had 0 spells in his deck that could kill me as I already explained he had wasted them all. The game was absolutely over as he had no minion bigger than a Piloted Shredder he could throw at me and even Unstable Portals had already been used.
Playing Ysera was the winning play 99,9% of the time.
