Mythos of Illuna + Radiate + Eternal Witness

Prerequisites

• There are permanents on the battlefield that enter the battlefield untapped and produce at least .

Steps

1. 1Cast Mythos of Illuna targeting anything but Eternal Witness, holding priority, and then cast Radiate targeting Mythos of Illuna.
2. 2When Radiate resolves you will have Mythos copies targeting every targetable permanent (except what the original Mythos card is targeting).
3. 3When each of the copies resolve, target Radiate in your graveyard with the new Eternal Witness token's ability and return Radiate to your hand.
4. 4Before the original Mythos of Illuna card resolves, cast Radiate again targeting Mythos by spending mana from the tokens you just created.
5. 5Repeat this process, effectively doubling the number of copies created, allowing you to return Radiate and another card with two Witness triggers.
6. 6Repeat.

Effects

• Infinite copies of all permanents
• Infinite recursion of most cards in your graveyard
• Infinite storm count
