Watermark
Watermarks are a distinguishing mark made into the text box area of cards.
Prerelease cards bear their expansion symbol as a watermark since Onslaught's Silent Specter, similarly release event cards bear their set symbol or logo. Other event cards not specific to a set bear the logo of that event, such as Friday Night Magic promo cards.
Some cards in the Ravnica block were given watermarks showing the guild from which they came. This is reprized in the Scars of Mirrodin block in which every single card that is not a Basic land or a Planeswalker bears the watermark of two warring factions: Phyrexia and Mirrodin.
