死亡綠洲

Text:

每當一個由你操控且非衍生物的生物死去時，將你牌庫頂的兩張牌置入你的墳墓場。然後將一張總魔法力費用小於死去者的生物牌從你的墳墓場移回你手上。
，犧牲死亡綠洲：你獲得若干生命，其數量等同於由你操控之生物中總魔法力費用最大者的數值。

Rulings:

• 4/17/2020 Because the triggered ability doesn’t target the creature card in your graveyard, you may choose one of the two cards you put there from your library.
• 4/17/2020 If a creature on the battlefield or a card in your graveyard has <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in its mana cost, X is considered to be 0.
• 4/17/2020 Use the converted mana cost of the creature as it last existed on the battlefield and the converted mana cost of the creature card as it exists in your graveyard to determine which cards may be returned to your hand. This may result in a creature’s death bringing itself back to your hand; perhaps it was one card of a merged creature, or it had become a copy of a more expensive creature.
• 4/17/2020 If Death’s Oasis becomes a creature, activating its last ability will cause its first ability to trigger.
