Four classes, six pairs
Ember is speed and burn, Root is healing and staying power, Mist is tricks, traps and card draw, Iron is armour and defence. Each pair of classes makes a different deck, and there is a starter deck for each of the six pairs to learn from. Read the class and deck guides for each one.
