Artifact, 4 (4)
{T}, Put the top card of your library into your graveyard: For each colored mana symbol in that card's mana cost, add one mana of that color to your mana pool. Activate this ability only any time you could cast an instant. (For example, if the card's mana cost is {3}{U}{U}{B}, you add {U}{U}{B} to your mana pool.)¹
Illus. Anthony S. Waters

• 10/4/2004: The ability is still a mana ability (and doesn't use the stack) even though you can only activate it when you could cast an Instant.
• 11/1/2005: If you flip over a hybrid card, you get one of either color mana, not both, for each mana symbol.
