掩襲（你可以支付此咒語的掩襲費用來施放它。如果你如此作，則它獲得敏捷異能，且在下個結束步驟開始時便需從戰場移回其擁有者手上。）

Rulings:

• 11/24/2014 If you choose to pay the dash cost rather than the mana cost, you’re still casting the spell. It goes on the stack and can be responded to and countered. You can cast a creature spell for its dash cost only when you otherwise could cast that creature spell. Most of the time, this means during your main phase when the stack is empty.
• 11/24/2014 If you pay the dash cost to cast a creature spell, that card will be returned to its owner’s hand only if it’s still on the battlefield when its triggered ability resolves. If it dies or goes to another zone before then, it will stay where it is.
• 11/24/2014 You don’t have to attack with the creature with dash unless another ability says you do.
• 11/24/2014 If a creature enters the battlefield as a copy of or becomes a copy of a creature whose dash cost was paid, the copy won’t have haste and won’t be returned to its owner’s hand.
