Whirlpool Galaxy

Suspend 3 —{u}(Rather than cast this card from
your hand, pay {u} and exile it with three time
counters on it. At the beginning of your upkeep,
remove a time counter. When the last is removed,
cast it without paying its mana cost.)
Search your library for a number of Islands
equal to your devotion to blue, put one onto the
battlefield and the rest into your hand, then
shuffle your library. (Each {u} in the mana costs
of permanents your control counts toward your
devotion to blue.)
