Q：倫敦調度到底是什麼？具體我什麼時候將牌放到牌庫底？更重要的，它和漿液粉末如何互動？

A：從核心系列2020開始，魔法風雲會確實是用了新的調度規則。新的調度方法叫倫敦調度是因為，這個方法在之前四月份倫敦舉行的傳奇錦標賽II上測試的。
新的調度規則如下運作：
在抓了第一個起手（通常是7張）後，牌手可以選擇保留或調度。如果牌手選擇調度這個起手，他將手牌洗回牌庫，然後再抓同樣數量的起手。之後牌手將等同于本回合調度次數的牌放到牌庫底。之後再調度也遵循同樣的步驟。
一個簡化流程是，如果你覺得你還需要再進行調度，可以直接將手牌洗回牌庫，先不將牌放到牌庫底，但是你需要保證能記住你知道已經調度過幾次了。
至於漿液粉末，它會在你可以選擇調度的時候生效，這個情況就是你將牌放到你牌庫底的時候。所以如果你調度了兩次之後手裡有漿液粉末想使用它，你首先將兩張牌放到牌庫底，然後放逐漿液粉末和另外四張牌，然後抽五張牌來替代它們。

Q: So what's the deal with the new London Mulligan? When exactly do I put cards on the bottom of my library? Most importantly, how does it work with Serum Powder?

A: Starting Core Set 2020, there is indeed a new mulligan procedure for all of Magic. The new procedure is colloquially known as the London Mulligan because it was tested out at Mythic Championship II in London this past April.

The new mulligan rules work as follows:
After drawing their first hand of (normally 7) cards, a player can choose to either keep that hand or to mulligan it. If the player chooses to mulligan the hand, they shuffle that hand back into their library and draw another full hand of the same number of cards as before. The player then puts a number of cards from their hand on the bottom of their library equal to the number of times they've taken a mulligan so far. Further mulligans proceed in the same manner.

A common shortcut in this process will be to just shuffle your hand back in without putting cards on the bottom if you know you're taking a mulligan further anyway, but if you do this be sure to keep track of how many times you've taken a mulligan so far.

As for Serum Powder, its effect can be applied when you normally choose to take a mulligan, which in this case is after you've put back cards on the bottom of your deck. So if you have taken a mulligan twice to a hand with Serum Powder in it and wanted to use it, you'd first put two other cards on the bottom of your library before exiling Serum Powder and the other four cards in your hand and drawing another five cards to replace them.
