Excellent card battler. There is no one meta or card to follow owing to each match being randomised with board modifiers. What works brilliantly in one match could be a struggle in the next. Plenty of tactics and deck make ups to keep things interesting as well with satisfying upgrades and generous unlocks. The micro transactions aren't intrusive and the daily challenges make the short bursts each day more enjoyable. Definitely one of the best free to play games out there and worth a go, even if just for the free tutorial season pass.
