PO3, Scrybe of Technology

When this creature transforms into PO3, Scrybe of Technology, place six time counters on it.
At the beginning of your upkeep, remove a time counter from this creature, and you get X {e}, where X is 6 minus the number of time
counters on this creature.
For each {1} in a spell's mana cost, you may pay {e} instead.
Pay {e}{e}: Create a 0/1 colorless Sentry Drone artifact creature token with "Whenever this creature blocks a creature, it deals 1 damage to that creature."
