424 - Costs
- 424.1 - A cost is an action or payment necessary to take another action or
to stop another action from taking place. [CompRules 2008/02/01]
- 424.2 - A player can't pay a cost unless he or she has the necessary
resources to pay it fully. For example, a player with only 1 life can't
pay a cost of 2 life, and a permanent that's already tapped can't be
tapped to pay a cost. See Rule 203, "Mana Cost and Color," and
Rule 403, "Activated Abilities." [CompRules 2007/05/01]
- 424.3 - Unpayable costs can't be paid. (See Rule 203.1b.)
[CompRules 2007/05/01]
- 424.4 - What a player actually needs to do to pay a cost may be changed or
reduced by effects. If the mana component of a cost is reduced to nothing
by cost reduction effects, it is considered to be {0}. Paying a cost
changed or reduced by an effect counts as paying the original cost.
[CompRules 2007/07/13]
Example: You play a spell with mana cost {W} that has kicker {1}. You
choose to pay the kicker, but a cost reduction effect means you spend
only {W} when paying for the spell. The spell's "if the kicker cost was
paid" effect will be applied. [CompRules 2007/05/01]
- 424.5 - If a cost includes a mana payment, the player paying the cost has a
chance to play mana abilities. Paying the cost to play a spell or
activated ability follows the steps in Rule 409.1f through Rule 409.1h.
