What must be in place

Codie does not have summoning sickness.
Power Artifact attached to Voltaic Construct.

How to execute it

  1. Activate Codie by paying {4} and tapping it, adding {W}{U}{B}{R}{G}.
  2. Activate Voltaic Construct by paying {1}, untapping Codie.
  3. Repeat.
  4. Once you have an arbitrarily large number of Codie triggers, you may cast any instant or sorcery spell by paying its mana cost.
  5. Codie triggers for each time you activated its ability.
  6. Resolve the first trigger, causing you to exile cards from the top of your library until you exile an instant or sorcery spell with lesser mana value, and allowing you to cast that spell without paying its mana cost.
  7. Repeat step 6 for each remaining trigger.
