Roots of Phyrexia

Hideaway 5 (When this enchantment enters,
look at the top five cards of your library, exile
one face down, then put the rest on the bottom in
a random order.)

At the beginning of your upkeep, you lose 1
life. Then you may play the exiled card
without paying its mana cost if its mana cost is
equal to or less than your devotion to Phyrexia.
