|
* 502.46. Convoke
|
|
* <p>
|
|
* 502.46a Convoke is a static ability that functions while the spell is on the stack. "Convoke"
|
|
* means "As an additional cost to play this spell, you may tap any number of untapped creatures
|
|
* you control. Each creature tapped this way reduces the cost to play this spell by {1} or by
|
|
* one mana of any of that creature's colors." Using the convoke ability follows the rules for
|
|
* paying additional costs in rules 409.1b and 4091f-h.
|
|
* <p>
|
|
* Example: You play Guardian of Vitu-Ghazi, a spell with convoke that costs {3}{G}{W}. You announce
|
|
* that you're going to tap an artifact creature, a red creature, and a green-and-white creature to
|
|
* help pay for it. The artifact creature and the red creature each reduce the spell's cost by {1}.
|
|
* You choose whether the green-white creature reduces the spell's cost by {1}, {G}, or {W}. Then
|
|
* the creatures become tapped as you pay Guardian of Vitu-Ghazi's cost.
|
|
* <p>
|
|
* 502.46b Convoke can't reduce the cost to play a spell to less than 0.
|
|
* <p>
|
|
* 502.46c Multiple instances of convoke on the same spell are redundant.
|
|
* <p>
|
|
* You can tap only untapped creatures you control to reduce the cost of a spell with convoke
|
|
* that you play.
|
|
* <p>
|
|
* While playing a spell with convoke, if you control a creature that taps to produce mana, you
|
|
* can either tap it for mana or tap it to reduce the cost of the spell, but not both.
|
|
* <p>
|
|
* If you tap a multicolored creature to reduce the cost of a spell with convoke, you reduce
|
|
* the cost by {1} or by one mana of your choice of any of that creature's colors.
|
|
* <p>
|
|
* Convoke doesn't change a spell's mana cost or converted mana cost.
