Marsch aus Velis Vel

Bestimme einen Nichtstandardlandtyp. Jedes Land des bestimmten Typs, das du kontrollierst, wird bis zum Ende des Zuges zu einer Kopie einer Kreatur deiner Wahl, die du kontrollierst, und erhält Eile bis zum Ende des Zuges.
Rückblende {4}{U} (Du kannst diese Karte aus deinem Friedhof für ihre Rückblendekosten wirken. Schicke sie danach ins Exil.)

Marche depuis Velis Vel

Choisissez un type de terrain non-base. Chaque terrain de ce type que vous contrôlez devient une copie d'une créature ciblée que vous contrôlez jusqu'à la fin du tour et acquiert la célérité jusqu'à la fin du tour.
Flashback {4}{U} (Vous pouvez lancer cette carte depuis votre cimetière pour son coût de flashback. Exilez-la ensuite.)

ヴェリズ・ヴェルからの進撃

あなたがコントロールしているクリーチャー１体を対象とする。非基本土地タイプ１つを選ぶ。ターン終了時まで、あなたがコントロールしていてそのタイプであるすべての土地はそのクリーチャーのコピーになり速攻を得る。
フラッシュバック{4}{U}（あなたの墓地にあるこのカードをフラッシュバック・コストで唱えてもよい。その後、これを追放する。）

March from Velis Vel

Choose a nonbasic land type. Each land you control of that type becomes a copy of target creature you control until end of turn and gains haste until end of turn.
Flashback {4}{U} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Modern Horizons 3 Commander

Choose a nonbasic land type. Each land you control of that type becomes a copy of target creature you control until end of turn and gains haste until end of turn.
Flashback {4}{U}

If the copied creature has {X} in its mana cost, X is 0.

"Flashback [cost]" means "You may cast this card from your graveyard by paying [cost] rather than paying its mana cost" and "If the flashback cost was paid, exile this card instead of putting it anywhere else any time it would leave the stack."

A spell cast using flashback will always be exiled afterward, whether it resolves, is countered, or leaves the stack in some other way.

Because the lands aren't entering the battlefield when they become copies of the creature, any "When [this creature] enters the battlefield" or "[This creature] enters the battlefield with" abilities of the copied creature won't apply.

If a card with flashback is put into your graveyard during your turn, you can cast it if it's legal to do so before any other player can take any actions.

If the copied creature is copying something else, then the lands become copies of whatever that creature copied.

The lands copy exactly what was printed on the original creature and nothing else (unless that permanent is copying something else; see below). They don't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, and so on.

To determine the total cost of a spell, start with the mana cost or alternative cost (such as a flashback cost) you're paying, add any cost increases, then apply any cost reductions. The mana value of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.

You can cast a spell using flashback even if it was somehow put into your graveyard without having been cast.

You must still follow any timing restrictions and permissions, including those based on the card's type. For instance, you can cast a sorcery using flashback only when you could normally cast a sorcery.
