Thassa's Oracle
Creature · Merfolk Wizard Game Changer
Players keep reaching for Thassa's Oracle whenever a Dimir or blue brew wants a way to turn a hollowed-out library into a win. It shows up in the Rogsi and Inalla conversations as the card that makes the Consultation line real, and in the Tamiyo brew as a proposed outlet for infinite mana. Six years on, it still defines the self-mill finish.

Thassa's Oracle is the best way to convert an empty library into a win, and nothing else at two mana does it as cleanly.
Around $18 and sitting at EDHREC rank 460
Plays well with
-
Demonic Consultation
Consultation exiles your library, and with your library empty, the Oracle's trigger wins the game on the spot.
-
Tainted Pact
Tainted Pact is the classic partner for the Oracle: exile your library, then cast the Oracle to win.
-
Laboratory Maniac
Maniac is the other half of the self-mill win: Thassa's Oracle wins with an empty library, while Maniac wins when you draw from one, giving you redundant outs.

Thassa's Oracle Rulings
- Jan 24, 2020
Colorless and generic mana symbols ({C}, {0}, {1}, {2}, {X}, and so on) in mana costs of permanents you control don't count toward your devotion to any color.
- Jan 24, 2020
Hybrid mana symbols, monocolored hybrid mana symbols, and Phyrexian mana symbols do count toward your devotion to their color(s).
- Jan 24, 2020
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.
- Jan 24, 2020
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.
- Jan 24, 2020
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.
