野生の心、セルヴァラ

他のクリーチャーが１体戦場に出るたび、そのパワーがそれ以外の各クリーチャーのパワーよりも大きいなら、それのコントローラーはカードを１枚引いてもよい。
{G}, {T}：あなたのマナ・プールに、望む色の組み合わせのマナＸ点を加える。Ｘはあなたがコントロールするクリーチャーの中の最大のパワーの値に等しい。

荒野之心塞瓦拉

每当另一个生物进战场时，如果其力量比每个其他生物都大，则其操控者可以抓一张牌。
{G}，{T}：加X点法术力到你的法术力池中，其颜色组合可任意选择，X为由你操控的生物中力量最大者的数值。

Selvala, Heart of the Wilds

Whenever another creature enters, its controller may draw a card if its power is greater than each other creature's power.
{G}, {T}: Add X mana in any combination of colors, where X is the greatest power among creatures you control.

Modern Horizons 3 Commander

Whenever another creature enters the battlefield, its controller may draw a card if its power is greater than each other creature's power.
{G}, {T}: Add X mana in any combination of colors, where X is the greatest power among creatures you control.

Commander Masters

If the new creature isn't on the battlefield as the first ability resolves, use its power when it left the battlefield to determine whether its controller may draw a card. Note that effects that reduced its power before it left the battlefield will apply.

Selvala's last ability is a mana ability. It doesn't use the stack and can't be responded to. If the greatest power among creatures you control is 0 or less at that time, no mana is added.

The new creature's power is compared to the power of each other creature on the battlefield as the first ability resolves. If another creature has the same or higher power than the new creature's power, no one may draw a card.
