Shield
Shield is a Passive Ability keyword.
It is present on Units.
Shield is formatted as "Shield [X]".
The X is referenced in the functional text of the ability.
The X is referred to as the Shield Value.
If X is omitted, it is presumed to be 1.
It is functionally short for "While I am a defender, I have +X [M]."
Being a defender means the Unit has gained the Defender designation during Combat. See rule 459. Combat for more information.
See also: 459.
Shield remains in effect as long as the Unit maintains the Defender designation.
If a Unit has Shield, or has been granted Shield, and is granted Shield by an additional source, the Shield Value of all granted Shield keywords is summed.
Example: Stalwart Poro has Shield. It is chosen as the target of Block, which says "Give a unit [Shield 3] and [Tank] this turn." After Block resolves, Stalwart Poro has Shield 4 this turn.
Shield, and whether or not a unit has Shield, is a characteristic of the Unit and may be checked or referenced by other Game Effects.
