Tempus, Eternal Chrono-lord

Indestructible
As long as your devotion to blue, red, white, and
green is at least 7, Tempus isn't a creature.
At the beginning of your upkeep, you may put a
time counter on yourself.
At the beginning of your end step, you may
remove any number of time counters from
yourself. If you do, create that many 1/1 colorless
Chrono Construct artifact creature tokens with
"This creature gets +1/+1 for each time counter
you have."
