Krosis, Time Goddess

As long as your devotion to blue, black, and red is
less than seven, Krosis isn't a creature.
Whenever you cast a spell, put a time counter on
Krosis, Time Goddess.
At the beginning of your upkeep, remove all time
counters from Krosis. If you removed seven or
more time counters this way, take an extra turn
after this one.
"The sands of time slip through mortal fingers, but for
I, they are but grains in the palm of a god."
