Thassa's Oracle
Here is a compulsory win condition card from Theros Beyond Death. This little Merfolk can win you games by simply looking at the cards from the top of your library.
Of course, devotion to blue color plays a huge part in all this, and that's why Thassa's Oracle will find a place in the Mono-Blue Devotion lists that run Thassa, God of the Sea and Master of Waves.
But Thassa's Oracle could also become the central spell in the self-mill lists that could easily trigger the win condition just as well.
