The 3 combo pieces

What must be in place

Codie does not have summoning sickness.
Agatha of the Vile Cauldron has power 2 or greater.

How to execute it

  1. Cast Chain Stasis by paying {U}, targeting Codie.
  2. Holding priority, activate Codie by paying at most {2} and tapping it, adding {W}{U}{B}{R}{G}.
  3. Resolve Chain Stasis, untapping Codie and causing you to pay {2}{U} to copy Chain Stasis, with the copy targeting Codie.
  4. Repeat from step 2.
  5. Once you have an arbitrarily large number of Codie triggers, you may choose not to copy Chain Stasis and cast any instant or sorcery by paying its mana cost.
  6. Codie triggers for each time you activated its ability.
  7. 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.
  8. Repeat step 6 for each remaining trigger.
  9. You may also repeat this combo for each instant and sorcery card in your hand as mana permits, and on subsequent turns.
