Watermark

A watermark is a faint imprint made into the text box area of certain 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. In the Scars of Mirrodin block every single card that was not a basic land or a planeswalker bore the watermark of one of the two warring factions: Phyrexians and Mirrans. The Ravnican watermarks were used agin in the Return to Ravnica block. Khans of Tarkir also used watermarks for the different clans, with Fate Reforged adding watermarks for the different dragons broods.
