Hey, in the first page, in that picture. 'Register' is spelled 'Regester'.
In the won fights and lost fights page, 'too' is written 'to'.
You should really fix these things, and for making the game a bit more popular, you gotta do some other things to.
Get a forum for yourselves, instead of this, a web address like forums.magicduel.com exists, but it is redirected to this place. You should change that.
Also in game development status page, the word 'I' is used, I think you'd better act as a team and not as a single person.
And get some more servers, name this server 1 and get some other ones too.
*These are my suggestions and I want to know what others will think about them. And I think this way because all popular games I've seen are like this. This is how we'll have more than 10 million people in a game, and here we only got a couple hundred. The game is nice, but things like this make it a bit unpopular*
