I played against a Mage recently. He played quest on 1, Explorer on 2, AI on 3, coined Thaurissan on 4 and followed up with Apprentice, two Flamewakers, two Frostbolts, a Ray of Frost and two Magic Tricks into two Arcane Missiles (I think he got an extra Magic Trick in there as well).

I had a 2/6 in play and was at 30 health. Then I was dead. On turn 5.

Yeah, I'll be happy to see Thaurissan and Flamewaker back out of Standard.
