Wernog leaves and enters the battlefield, triggering its ability twice, causing you to create at least two Clue artifact tokens.
Activate Clock of Omens by tapping the Clues, untapping Chromatic Orrery.
Repeat.
Because your opponents must choose to either let themselves and you investigate, or lose life, this combo will very likely result in infinite Clue tokens for you and your opponents.
Once you have infinite mana, you may use Chromatic Orrery's second ability instead to draw infinite cards.
