This was pretty cool vs. a freeze/Alexstrasza/burn deck. I got Ice Block from a Thoughtsteal. Next turn he played Alexstrasa. On my turn I killed the Alexstrasa, played ice block, and hero powered myself back to 17. He conceded. Guess he knew it was ice block and didn't think he could kill me twice while I heal myself every turn. Always fun to Thoughtsteal something that really counters their strategy.
