Legacy (keyword)

The Legacy keyword ability is a nod to Legacy-style board games. It is a static ability that allows you to permanently change the rules connected to a card by permanently marking it with a pen.

The mechanic appeared on two test cards in the Mystery Booster set.

Rulings

 * Once you've marked a card, you can't change it, even between games. It remains part of that physical card
 * If an object becomes a copy of an object with a word blank, the value in that blank is copied.
 * If an object without nodes becomes a copy of an object with nodes, the copy has no nodes. A cost to mark one of its nodes can't be paid.

Trivia
The plot booster is another concept derived from Legacy-style board games.
