Angel of Time

Flying
Flash, phase 3: {u} (When this creature becomes
target of a spell or an ability an opponent controls or
if you pay its phase costs, exile it with 3 phase counters
on it. Remove a phase counter at the beginning of each
turn. When there are no counters left, put it back onto
the battlefield.)

You may play creatures with phase counters on
them from exile by paying their mana costs as
though they had flash.
