user
[START OF COMBO]This combo can be formed with Codie, Vociferous Codex, Filigree Sages, Heartstone

Color identity: WUBRG
Mana cost: {3}, plus enough mana to pay for the nonland card's mana cost minus {W}{U}{B}{R}{G}
Steps:
  1. Activate Codie by paying {3} and tapping it, adding {W}{U}{B}{R}{G}.
  2. Activate Filigree Sages by paying {1}{U}, untapping Codie.
  3. Repeat as desired, skipping step 2 on the final iteration.
  4. Once you have an arbitrarily large number of Codie triggers, cast any spell by paying its mana cost, reduced by the {W}{U}{B}{R}{G} added in step 1.
  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.
  8. You may also repeat this combo for each instant and/or sorcery card in your hand as mana permits, and on subsequent turns.[END OF COMBO STEPS]

  - Cast all instants and sorceries in your library with mana value less than instants and/or sorceries you cast[END OF COMBO RESULT][END OF COMBO]
