/**
|
|
* 502.59. Suspend
|
|
* <p>
|
|
* 502.59a Suspend is a keyword that represents three abilities. The first is a
|
|
* static ability that functions while the card with suspend is in a player's
|
|
* hand. The second and third are triggered abilities that function in the
|
|
* removed-from-the-game zone. "Suspend N--[cost]" means "If you could play this
|
|
* card from your hand, you may pay [cost] and remove it from the game with N
|
|
* time counters on it. This is a special action that doesn't use the stack,"
|
|
* and "At the beginning of your upkeep, if this card is suspended, remove a
|
|
* time counter from it," and "When the last time counter is removed from this
|
|
* card, if it's removed from the game, play it without paying its mana cost if
|
|
* able. If you can't, it remains removed from the game. If you play it this way
|
|
* and it's a creature, it gains haste until you lose control of it."
|
|
* <p>
|
|
* 502.59b A card is "suspended" if it's in the removed-from-the-game zone, has
|
|
* suspend, and has a time counter on it.
|
|
* <p>
|
|
* 502.59c Playing a spell as an effect of its suspend ability follows the rules
|
|
* for paying alternative costs in rules 409.1b and 409.1f-h.
|
|
* <p>
|
|
* The phrase "if you could play this card from your hand" checks only for
|
|
* timing restrictions and permissions. This includes both what's inherent in
|
|
* the card's type (for example, if the card with suspend is a creature, it must
|
|
* be your main phase and the stack must be empty) and what's imposed by other
|
|
* abilities, such as flash or Meddling Mage's ability. Whether you could
|
|
* actually follow all steps in playing the card is irrelevant. If the card is
|
|
* impossible to play due to a lack of legal targets or an unpayable mana cost,
|
|
* for example, it may still be removed from the game with suspend.
|
|
* <p>
|
|
* Removing a card from the game with its suspend ability is not playing that
|
|
* card. This action doesn't use the stack and can't be responded to.
|
|
* <p>
|
|
* If a spell with suspend has targets, the targets are chosen when the spell is
|
|
* played, not when it's removed from the game.
|
|
* <p>
|
|
* If the first triggered ability of suspend is countered, no time counter is
|
|
* removed. The ability will trigger again during its owner's next upkeep.
|
|
* <p>
|
|
* When the last time counter is removed from a suspended card, the second
|
|
* triggered ability of suspend will trigger. It doesn't matter why the time
|
|
* counter was removed or whose effect removed it. (The _Time Spiral_ reminder
|
|
* text is misleading on this point.)
|
|
* <p>
|
|
* If the second triggered ability of suspend is countered, the card can't be
|
|
* played. It remains in the removed-from-the-game zone without any time
|
|
* counters on it for the rest of the game, and it's no longer considered
|
|
* suspended.
|
|
* <p>
|
|
* If the second triggered ability of suspend resolves, the card's owner must
|
|
* play the spell if possible, even if that player doesn't want to. Normal
|
|
* timing considerations for the spell are ignored (for example, if the
|
|
* suspended card is a creature and this ability resolves during your upkeep,
|
|
* you're able to play the card), but other play restrictions are not ignored.
|
|
* <p>
|
|
* If the second triggered ability of suspend resolves and the suspended card
|
|
* can't be played due to a lack of legal targets or a play restriction, for
|
|
* example, it remains in the removed-from-the-game zone without any time
|
|
* counters on it for the rest of the game, and it's no longer considered
|
|
* suspended.
|
|
* <p>
|
|
* As the second triggered ability of suspend resolves, if playing the suspended
|
|
* card involves an additional cost, the card's owner must pay that cost if
|
|
* able. If they can't, the card remains removed from the game. If the
|
|
* additional cost includes mana, the situation is more complex. If the player
|
|
* has enough mana in their mana pool to pay the cost, that player must do so.
|
|
* If the player can't possibly pay the cost, the card remains removed from the
|
|
* game. However, if the player has the means to produce enough mana to pay the
|
|
* cost, then they have a choice: The player may play the spell, produce mana,
|
|
* and pay the cost. Or the player may choose to play no mana abilities, thus
|
|
* making the card impossible to play because the additional mana can't be paid.
|
|
* <p>
|
|
* A creature played via suspend comes into play with haste. It still has haste
|
|
* after the first turn it's in play as long as the same player controls it. As
|
|
* soon as another player takes control of it, it loses haste.
