Dark Summoner, its a dark fantasy monster battle game for Android and Ipad/Iphones. Here's an article I found with a better description of the game.
Dark Summoner for iPhone – Game Review | AppShrink.com
I never really played these type of games but iluvfish2 recommended it in another thread and i got hooked once i got the hang of it. Try it out its FREE and if you dont like it just uninstall it, nothing to lose. If you do join please help me out and enter my player ID when prompted while creating your account. You'll get 3 Summons which is basically 3 monster cards to start you off and I'll also receive the same. Post or PM me here or leave a msg in game if you need help getting the hang of it once you join. Thanks
