Der Meister der Schlüssel

Fliegend
Wenn Der Meister der Schlüssel ins Spiel kommt, lege X +1/+1-Marken auf ihn und mille zweimal X Karten.
Jede Verzauberungskarte in deinem Friedhof hat Befreiung. Die Befreiungskosten sind gleich den Manakosten der Karte plus „Schicke drei andere Karten aus deinem Friedhof ins Exil." (Du kannst Karten aus deinem Friedhof für ihre Befreiungskosten wirken.)

Le Maître des clés

Vol
Quand Le Maître des clés arrive, mettez X marqueurs +1/+1 sur lui et meulez deux fois X cartes.
Chaque carte d'enchantement dans votre cimetière a l'échappée. Le coût d'échappée est égal au coût de mana de la carte plus l'exil de trois autres cartes de votre cimetière. (Vous pouvez lancer des cartes depuis votre cimetière pour leur coût d'échappée.)

鍵の主

飛行
鍵の主が戦場に出たとき、これの上に＋１/＋１カウンターＸ個を置き、Ｘの２倍に等しい枚数のカードを切削する。
あなたの墓地にある各エンチャント・カードはそれぞれ脱出を持つ。脱出コストは、そのカードのマナ・コストに「あなたの墓地にありこれでないカード３枚を追放する。」を追加したものに等しい。（あなたの墓地にあるカードを脱出コストで唱えてもよい。）

The Master of Keys

Flying
When The Master of Keys enters, put X +1/+1 counters on it and mill twice X cards.
Each enchantment card in your graveyard has escape. The escape cost is equal to the card's mana cost plus exile three other cards from your graveyard. (You may cast cards from your graveyard for their escape cost.)

Duskmourn: House of Horror Commander

After an escaped spell resolves, it returns to its owner's graveyard if it's not a permanent spell. If it is a permanent spell, it enters and will return to its owner's graveyard if it dies later. It can escape again.

Escape's permission doesn't change when you may cast the spell from your graveyard.

If The Master of Keys is no longer on the battlefield when its second ability resolves, you'll still mill twice X cards.

If a card has multiple abilities giving you permission to cast it, such as two escape abilities or an escape ability and a flashback ability, you choose which one to apply. The others have no effect.

If a card has no mana cost, its escape cost is an unpayable cost, so you can't cast it for that cost.

If a card with escape is put into your graveyard during your turn, you'll be able to cast it right away if it's legal to do so, before an opponent can take any actions.

If a spell you're casting with escape has an additional cost of discarding cards or sacrificing permanents, you may exile cards discarded or sacrificed this way to pay that part of its escape cost.

If you cast a spell with its escape permission, you can't choose to apply any other alternative costs or to cast it without paying its mana cost. If it has any additional costs, you must pay those.

If you're casting a Room with escape, you choose which half to cast, then pay the appropriate cost plus exiling three cards. The same is true for split cards, adventurer cards, and prototype cards.

Once you begin casting a spell with escape, it immediately moves to the stack. Players can't take any other actions until you're done casting the spell.

To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as an escape cost), add any cost increases, then apply any cost reductions. The mana value of the spell remains unchanged, no matter what the total cost to cast it was and no matter whether an alternative cost was paid.
