血清の粉末

{T}：あなたのマナ・プールに{C}を加える。
あなたがマリガンを行えてあなたの手札に血清の粉末があるときならいつでも、あなたはあなたの手札からカードをすべて追放し、その後その数に等しい枚数のカードを引いてもよい。（マリガンの手順に加えてこれを行える。）

浆液粉末

{T}：加{C}到你的法术力池中。
如果你处于能够再调度的时机，且浆液粉末在你手上，你可以放逐你手上的所有牌，然后抓等量的牌。（你除了再调度之外，也可以如此作。）

Serum Powder

{T}: Add {C}.
Any time you could mulligan and this card is in your hand, you may exile all the cards from your hand, then draw that many cards. (You can do this in addition to taking mulligans.)

Mystery Booster 2

{T}: Add {C}.
Any time you could mulligan and Serum Powder is in your hand, you may exile all the cards from your hand, then draw that many cards. (You can do this in addition to taking mulligans.)

Iconic Masters

{T}: Add {C} to your mana pool.
Any time you could mulligan and Serum Powder is in your hand, you may exile all the cards from your hand, then draw that many cards. (You can do this in addition to taking mulligans.)

Darksteel

{T}: Add {1} to your mana pool.
Any time you could mulligan and Serum Powder is in your hand, you may remove your hand from the game, then draw that many cards. (You can do this in addition to taking mulligans.)

The cards in your hand are exiled for the rest of the game; they aren't shuffled back into your library if you take another mulligan. Cards exiled are always face up unless the effect that exiled them says they aren't. Be sure to return those cards to your deck for your next game.

You can use Serum Powder's second ability only while it's in your hand. If this card is in your hand, you can choose either to mulligan or to use Serum Powder's ability. Using the ability doesn't prevent you from taking further mulligans, and taking a mulligan doesn't prevent you from using a Serum Powder's ability if you happen to draw one in your new hand.
