What is Solo Play? Edit
In Solo Play mode you can practice your skills against NPC rivals. There are 3 difficulties: bronze, silver and gold. Three more difficulties will come soon.
When defeating an enemy rival for the first time in a difficulty you will be rewarded a gold reward chest. Any further wins will grant you a silver reward chest. As anywhere on defeat you will be rewarded a bronze reward chest. If you defeated all 4 legends in a difficulty you will be rewarded a card pack. After that you can not receive a card pack for defeating all 4 legends in that category again.
