Red Ability Cards are a type of Ability Card and just like the other ones, you can only have one red card in the Game. Red Cards are Ability Cards that most often trigger when you roll your Bakugan and many of the cards affect the roll as well like placing a Bakugan on the field or allowed shifting to another Gate Card if you land on the wrong one. Red abilities also have very powerful cards but often a certain condition has to be met on your roll and if you miss roll, you may have just wasted an Ability Card so if you are a beginner, try using some Red Ability Cards that don't require something specific.
