Welcome to the page for the booster cube!
In this cube, Booster Tutor can be played for 1 of any color, and when you play it, the card you tutor can permanently replace a card that's already in the cube. As a result, this cube should evolve over time as you play it!
This page is my version of the cube, but you can make your own by opening some random boosters and starting with that as the base. The tutors and replacement should tailor the cube to your group and your playstyle.
