In Rage of Bahamut on the Android, iPad, iPhone, and iPod Touch, you have a card that is designated as your “leader” in battles and quests.
You can change this leader at any time if you’d like, and here’s how to do it:
1. Press on the My Page link at the bottom. (If you see the card you want to set as the leader in those five at the top of My Page, press it and skip to step 4)
2. Near the bottom of this page, press the Cards link where it shows you how many cards are in your deck.
3. Find the card you would like make the leader and press on the name of the card to view it. Using the filters and sorting functions will help narrow down your search.
4. Press the Set as Leader button.
