Joymax, the developer behind the massive old school MMORPG Silkroad Online, has just released Fantasy Stars: Battle Arena. This is a Clash Royale-style arena battler that pits you against another player to see who can build the strongest deck.
You’ll build a deck of troop cards that you’ll collect and upgrade as you play. You’ll then drop them onto the battlefield against your opponent. As you progress, you’ll unlock chests that provide you with more cards and the resources to upgrade your current cards. You can get it on Google Play
