This is my favourite game on Mobile Devices. It's a TCG with dungeons where you "walk" compared to Rage of Bahamut. The interface is also much better than the really annoying one of RoB. You get cards very fast and without paying, you can have strong monsters which you can use to encounter in PVP and Special events. The events happen quite often, so it never gets boring. As the game is new, they add frequently new cards and updates, like the latest trading feature.
So just try it guys! And enter my code 7YmfuS after the tutorial which will ad you an me
