2016-04-08 : Casting a spell for an alternative cost, such as a madness cost, doesn't change its mana value. For example, casting Twins of Maurer Estate (a card with mana cost {4}{B} and madness cost {2}{B}) for its madness cost will not cause Bygone Bishop's ability to trigger.

2016-04-08 : If you sacrifice a Clue for another card's cost or effect, such as that of Angelic Purge or Tamiyo's Journal, you can't also pay {2} and sacrifice it to draw a card.

2016-04-08 : The token is named Clue Token and has the artifact subtype Clue. Clue isn't a creature type.

2016-04-08 : The tokens are normal artifacts. For example, they can be sacrificed to cast Angelic Purge or targeted by Root Out.
