Transform

Some cards can transform. When a card transforms, it flips to its opposite side.

In Attack on Titan: Battle for Humanity, for Characters that transform, their abilities will tell you how to change them into their mighty Titan forms! For example, after using Reiner Braun’s Response ability, if either player has 9 or more foundations in their stage, Reiner will transform into Reiner, Armored Titan!

Shift

Attacks that can transform, such as Attack Titan Attacks!, have the Shift ability. When you clear Attack Titan Attacks! from your card pool during the End Phase, you can choose to transform it to its Backup side and build it in your stage.
