|
* 702.46. Offering #
|
|
* 702.46a Offering is a static ability of a card that functions in any zone from which
|
|
* the card can be cast. "[Subtype] offering" means "You may cast this card any time you
|
|
* could cast an instant by sacrificing a [subtype] permanent. If you do, the total cost
|
|
* to cast this card is reduced by the sacrificed permanent's mana cost." #
|
|
*
|
|
* 702.46b The permanent is sacrificed at the same time the spell is announced (see rule 601.2a).
|
|
* The total cost of the spell is reduced by the sacrificed permanent's mana cost (see rule 601.2e). #
|
|
*
|
|
* 702.46c Generic mana in the sacrificed permanent's mana cost reduces generic mana
|
|
* in the total cost to cast the card with offering. Colored mana in the sacrificed
|
|
* permanent's mana cost reduces mana of the same color in the total cost to cast the
|
|
* card with offering. Colored mana in the sacrificed permanent's mana cost that doesn't
|
|
* match colored mana in the colored mana cost of the card with offering, or is in excess
|
|
* of the card's colored mana cost, reduces that much generic mana in the total cost. #
