A Premium Campaign adds an additional layer of rewards that you will unlock as you progress through the army’s campaign nodes. These rewards are tailored to accelerate completing your deck with additional in-game currency and wildcards - including a Legendary one in the very first node!

Moreover, Premium Campaigns will provide free campaign points for that army as part of your login bonus every day. That means you will be reaping the rewards forever, regardless of which army you have currently chosen as your preferred one, without having to play or meet any criteria other than logging in and collecting them!

If you want to get the most out of your campaigns, upgrade them to Premium Campaigns via the optional purchase found in the Campaign screen.
