Thank you for all the feedbacks,

@fil_razorback :
Tha hardest thing in the game is to find a good build for your deck, the starter deck will probably lose most of the games above level 1

@Soundsbien :
I will add the option to switch to another element soon, it's in the "to do" list, when a creature is copied, the poison status is also copied, the problem is that the poison icon (and the frozen animation too) do not re-appear on the new creature... I'll try to fix that.

And thank you also for the other comments/suggestion, I have a very long list of things to fix/improve, I thought that having a level4 with the option to play against other players deck was the most important thing to add.
