Teferi's Isle

Legendary Land
Phasing (This phases in or out before you untap during each of your untap steps. While it's phased out, it's treated as though it doesn't exist.)

Teferi's Isle enters the battlefield tapped.

{T}: Add {U}{U} to your mana pool.¹
The three wizards knew only that this isle held a great mystery-and that patience alone would solve it.
