Creating characters that take more than 1 space is usually ill-advised. It complicates game play too much. I've tried it on a couple of occassions and after many hours of wasted effort; always come to the same conclusion. Keep each character as 1 space. It keeps the ED engine in tact.

I'm not saying it can't be done, but I find it counter-intuitive and diminishes real ED gameplay mechanics. I find the "1 character-1 space" as a constant to ED game mechanics. Once you go outside that, you're not playing Epic Duels anymore.

This is just my opinion. But, I would just make the character take 1 space and make a awesome deck. You've got some nice cards there.
