生物 ～人鱼／法术师
当塔萨的先知进战场时，检视你牌库顶的X张牌，X为你的蓝色献力。将其中至多一张置于你的牌库顶，其余的牌则以随机顺序置于你的牌库底。若X等于或大于你牌库中牌的数量，则你赢得这盘游戏。（由你操控之永久物的法术力费用当中每含有一个，你的蓝色献力就加一。）
Oracle text (EN)
Creature — Merfolk Wizard
When this creature enters, look at the top X cards of your library, where X is your devotion to blue. Put up to one of them on top of your library and the rest on the bottom of your library in a random order. If X is greater than or equal to the number of cards in your library, you win the game. (Each in the mana costs of permanents you control counts toward your devotion to blue.)

Rulings
-
Colorless and generic mana symbols (
, 
, 
, 
, 
, and so on) in mana costs of permanents you control don't count toward your devotion to any color. -
If you put an Aura on an opponent's permanent, you still control the Aura, and mana symbols in its mana cost count towards your devotion.
-
If an activated ability or triggered ability has an effect that depends on your devotion to a color, you count the number of mana symbols of that color among the mana costs of permanents you control as the ability resolves. The permanent with that ability will be counted if it's still on the battlefield at that time.
-
If your devotion to blue is zero at the time the triggered ability of Thassa's Oracle resolves, you don't look at or move any cards in your library. If you have no cards in your library, you win the game.
-
Hybrid mana symbols, monocolored hybrid mana symbols, and Phyrexian mana symbols do count toward your devotion to their color(s).
-
Mana symbols in the text boxes of permanents you control don't count toward your devotion to any color.
