I'm sure you have all seen the spoiled cards. Lance looks to become a lot more prevalent after the release. Rather than nerfing all the cards they can do something to lance himself. Maybe story lines he dies. Then ban him and create some other rogue hero? I'm not seeing much other options. Nerfing cards over and over due to a hero that only gains in power as new sets come out reduces the attractiveness of the game itself.
