Power Cards are pre-made Combo cards that can be played in one turn during Battle.
Because Power Cards can be played without creating a Combo in battle, their swiftness is an advantage. Power Cards are generally not as powerful as the original Combo and lack the ability to benefit from Combo related skills.
Because a Power Card is already combo'd, it cannot be researched with any additional cards. "Power Cards don't have combos."
Power cards are marked in battle with Combo icon ( 
) once played in Battle.
You can obtain Power Cards by participating in events, collecting Power Stones, or by purchasing them in Bundles/Boxes in the Shop.
Power Cards are boosted by Combo Mastery.
