Did three arena runs today. First was a pretty crappy priest deck which went 4-3. Then I picked Warlock for the first time in arena and went 6-3 which is pretty damn good for me. Then I went 2-3 with quite possibly the worst deck ever. Mage with only one spell and all the cards I got offered were sub par.
Oh well. I need to arena more. Think I've done less than 10 runs.
The hold mechanic looks like it could be interesting for both players. Gives me more information about the possible cards in his hand if his battlecry that depends upon holding a dragon goes off / doesn't.
