Can't get enough card-based gaming on your iPad? Then you'll probably want to register for the chance to get one of 100 places in the closed beta test of another one, Earthcore: Shattered Elements.

Earthcore: Shattered Elements is a - you guessed it - card battler that uses a rock-paper-scissors style system based around the three elements of Earth, Fire, and Water. We showed you a trailer for it earlier this month, remember?

An interesting feature is the crafting tool, which allows you to craft your own cards. Apparently there are over 500,000 cards just waiting to be crafted.

Check out this rather dramatic trailer to whet your appetite for some tappy card-based battling, then sign up for the Beta here.
