That's where I was thinking that having more cards of EARTH with 12 life or better might be the way to tackle it since the earth cards get the 5 strength bonus. However since I haven't actually been there to see what really goes on, I'm just guessing. I think it would be VERY helpful to be able to see what future challenges look like so we can plan our strategies ahead of time and plan to upgrade the cards we think we may need. Under the current system, you need to be dying to find out (literally).
