As far as gameplay, it seems to be EXACTLY like magic. Thats a plus and a minus in my books. I realyl enjoyed magic, I stopped playing because I had no-one to play with. Id liek for a new game to be new, but if I have to revisit an old game, I would be happy to do so with Magic with a different skin. IW kicks ass with its simultaneous turns and initative system.
The cards dont level up, they gain experience and once they "level up" they "evolve" into full art cards. They dont get any more powerful or anything stupid like that.
If you want the stupid stuff, you need to go raiding and get equipment. Then depending on the equipment you have and the cards you use, you can turn cards ridiculously powerful. It has a PvE game, so its not just grinding games out against people.
Of course, the PvP aspect wouldnt be fun if your opponent just has these stupid powerful equipment, so no equipment is allowed in PvP.
I like the blend of the TCG and the MMO, which will give me somethign to do rather than the same thing over and over, which I am really starting to feel with IW atm.
