2017/09/29
原文If you cast one of the revealed cards, you do so as part of the resolution of the triggered ability. You can't wait to cast it later in the turn. Timing permissions based on the card's type are ignored, but other restrictions (such as "Cast [this card] only during combat") are not.
2017/09/29
原文If you cast a card "without paying its mana cost," you can't pay any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, such as that of Costly Plunder, those must be paid to cast the card.

原文The mana value of a split card, such as cards with aftermath from the Amonkhet block, is based on the combined mana cost of its two halves. The mana value of the resulting spell is based only on the half you cast.
