Let's design a fucking game together

Hi nerds. I want to design a website with a small card game (like Yugi oh or Magic or that kind of shit) but the thing is has to:
* Have a fixed set of cards (that is no custom cards)
* Games should end in a range of 10 - 20 turns mostly.
Since you are nerds and expert on this kind of shit and enjoy the autism of designing things, i wonder if you could kindly help me.

What matter is the RULES, nerds. The drawings come later. In can be cats, zombie hamsters, of anime girls. After you have the rules set, anything can go in the cards.
