What it does
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 blue mana in the mana costs of permanents you control counts toward your devotion to blue.)

Where it came from
Thassa's Oracle was originally introduced in the 2020 expansion Theros Beyond Death. Designed as a blue creature representing the god of the sea, the card became infamous for its ability to win the game instantly by checking the player's remaining library, a mechanic that fundamentally altered the competitive landscape of formats like Commander and Pioneer.
The Mystery Booster 2 version, appearing as card 175, serves as a recent reprinting of this influential spell. The original design by Wizards of the Coast aimed to capture the theme of divination and foresight within the Theros setting, though its mechanical efficiency quickly overshadowed its narrative intent, leading to its status as one of the most debated cards in the history of Magic: The Gathering.
