It's a decent Hearthstone clone (with a different laning approach), and it's rather f2p friendly. It does have some flaws: 1. Since minions attack their lanes every turn, it is very hard to make a new minion stay on the board without removal spells 2. Big creatures can become insurmountable, so it's very hard to reset the board without Meteor Swarm 3. Your own minions clog up lanes, making for boring turns of no action, just pressing "attack" 4. Not enough units yet, so battles feel samey fast
