It's a great concept. But since you can't see what the computer actually plays (outside of monsters/dinosaurs) it's really frustrating to watch your side of the board die without knowing how. Also, you might want to create a tutorial explaining how the actual process of upgrading from egg to the stages works, cause I spent quite a while having the 'eggsack' power to play one, but I couldn't for whatever reason.
I like it overall, just make it more user-friendly.
