Mahlstrom-Nexus

Der erste Zauberspruch, den du pro Zug wirkst, hat Kaskade. (Wenn du deinen ersten Zauberspruch wirkst, schicke solange die oberste Karte deiner Bibliothek ins Exil, bis du eine Nichtland-Karte ins Exil schickst, die weniger kostet als der erste Zauberspruch. Du kannst sie wirken, ohne ihre Manakosten zu bezahlen. Lege die so ins Exil geschickten Karten in zufälliger Reihenfolge unter deine Bibliothek.)

Nexus du Maelstrom

Le premier sort que vous lancez à chaque tour a la cascade. (Quand vous lancez votre premier sort, exilez les cartes du dessus de votre bibliothèque jusqu'à ce que vous exiliez une carte non-terrain d'un coût inférieur. Vous pouvez la lancer sans payer son coût de mana. Mettez les cartes exilées au-dessous de votre bibliothèque dans un ordre aléatoire.)

大渦のきずな

各ターン、あなたが最初に唱える呪文は続唱を持つ。（あなたが最初の呪文を唱えたとき、コストがこれより低く土地でないカードが追放されるまで、あなたのライブラリーの一番上からカードを１枚ずつ追放する。あなたはそれをそのマナ・コストを支払うことなく唱えてもよい。追放したカードをあなたのライブラリーの一番下に無作為の順番で置く。）

涡心连结点

你每回合中施放的第一个咒语具有倾曳异能。（当你施放你的第一个咒语时，从你的牌库顶开始放逐牌，直到放逐一张费用比该咒语低的非地牌为止。你可以施放该牌，且不需支付其法术力费用。将所放逐的牌以随机顺序置于你的牌库底。）

Maelstrom Nexus

The first spell you cast each turn has cascade. (When you cast your first spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)

Dominaria United Commander

The first spell you cast each turn has cascade. (When you cast your first spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom of your library in a random order.)

Double Masters

The List

Alara Reborn

The first spell you play each turn has cascade. (When you play your first spell, remove cards from the top of your library from the game until you remove a nonland card that costs less. You may play it without paying its mana cost. Put the removed cards on the bottom in a random order.)

If the first spell you cast in a turn already has cascade, both cascade abilities will trigger separately. Deal with them one at a time: First one cascade ability will resolve, and you'll cast the applicable card if you want. That new spell will resolve. Then the other cascade ability will resolve in the same way. Finally, the original spell will resolve.

This effect takes into account spells that were cast earlier in the turn before Maelstrom Nexus entered the battlefield, including any spells still on the stack. If you've already cast any spells that turn (including Maelstrom Nexus itself), this ability won't give any of your spells cascade that turn.

A spell's mana value is determined only by its mana cost. Ignore any alternative costs, additional costs, cost increases, or cost reductions.

Cascade triggers when you cast the spell, meaning that it resolves before that spell. If you end up casting the exiled card, it will go on the stack above the spell with cascade.

Due to a 2021 rules change to cascade, not only do you stop exiling cards if you exile a nonland card with lesser mana value than the spell with cascade, but the resulting spell you cast must also have lesser mana value. Previously, in cases where a card's mana value differed from the resulting spell, such as with some modal double-faced cards or cards with an Adventure, you could cast a spell with a higher mana value than the exiled card.

If a spell with cascade is countered, the cascade ability will still resolve normally.

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.

If you cast a card "without paying its mana cost," you can't choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, you must pay those to cast the card.

The mana value of a split card is determined by the combined mana cost of its two halves. If cascade allows you to cast a split card, you may cast either half but not both halves.

When the cascade ability resolves, you must exile cards. The only optional part of the ability is whether or not you cast the last card exiled.

You exile the cards face up. All players will be able to see them.
