Thank you

You're probably right on all points. I don't know any lawyer versed in this international business :) but I'll consider it.

What I really like is the "punching" effect the cards do in HearthStone. And the use of the "Coin" card for balance.

Other than that... it would basically be another card game with unique minions, artwork and design. I don't know. It's so fuzzy in my mind what's allowed and what isn't allowed :D - I don't want to annoy anyone, especially blizzard - if they had a browser-based HearthStone I would probably just play that instead :)))

But thanks a lot for the advice!!
