如果你以「不需支付其法术力费用」的方式来施放牌，就无法支付任何替代性费用。不过，你能够支付额外费用。如果此牌含有任何强制性的额外费用，则你必须支付之，才能施放此牌。
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, those must be paid to cast the card. -

如果该牌的法术力费用中包含{X}，则你在以「不需支付其法术力费用」的方式施放它时必须将X的值选为0。
If the card has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost. -

你可以放逐由你操控的衍生物，来充当所需之材料。不过由于衍生物不是牌，且不会留在放逐区中，因此任何提及你「用以化炼」其背面之异能会看不到它们。
You may exile tokens you control as part of the materials required. However, because they aren't cards and won't stay in exile, any abilities that refer to what you "used to craft" the back faces won't refer to anything. -

你是于宇金触媒的起动式异能结算时，才决定是否要施放所放逐的牌。如果你如此作，则你是在该异能结算的中途一并施放之。你不能等到本回合内稍后时段再施放。不会受到牌张类别的施放时机限制。
You choose whether or not to cast the exiled card as Cosmium Catalyst's activated ability resolves. If you do, you do so as part of the resolution of that ability. You can't wait to cast it later in the turn. Timing restrictions based on the card's type are ignored. -

有些具化炼异能之牌的背面会提到「用以化炼」它的牌。这指的是在支付其正面的化炼异能之费用时所放逐的牌。只要满足以下条件，这些所放逐的牌便视作「用以化炼」该永久物：（1）它们仍持续被放逐；（2）该永久物仍在战场上，包括该永久物的操控者改变，或其特征有所变化（例如受复制效应影响）之情形。
The back faces of some cards with craft refer to cards "used to craft" it. This refers to the cards exiled as part of the cost of the craft ability of the front face. Those cards are considered to be "used to craft" that permanent as long as they remain exiled and the permanent remains on the battlefield, even if the permanent's controller changes or some of its characteristics change (because of a copy effect, for example.) -

如果材料的部分要求多个物件，则你可以从由你操控的永久物中放逐一部分，之后再放逐你的坟墓场中相应类别之牌来补齐剩下的部分。所放逐的不必全是永久物，也不必全是你坟墓场中的牌。
If the materials required include multiple objects, you may exile some of them from among permanents you control and the rest from among cards in your graveyard. You don't have to choose all permanents or all cards from your graveyard. -

如果某张非转化式双面牌成为具化炼异能的牌之复制品，则当你起动化炼异能时，该牌会留在放逐区。它不会返回战场。
If a card that isn't a transforming double-faced card becomes a copy of a card with craft, it'll stay in exile if you activate the craft ability. It won't return to the battlefield.
