Draw two cards. You may put a land card from your hand onto the battlefield.
"At first, the equations were simply numbers. But in those numbers, I saw a story, and in that story I saw a pattern, and suddenly it all fit together!"
Putting a land card from your hand onto the battlefield is not the same as playing a land. You may do it even if you have already played a land on your turn, or if you're casting Eureka Moment on your opponent's turn.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
