Mythos of Illuna, Radiate, and Possessed Skaab

Prerequisites

• Skaab on the battlefield
• Mythos and Radiate in hand
• available
• Enough immediate sources of mana on the battlefield (ETB untapped lands, artifacts that tap for mana, etc) to produce

Steps

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

Results

• Infinite copies of all targetable permanents
• Return any number of instant and sorcery and creature cards (except Mythos of Illuna) from your graveyard to your hand any number of times
• Infinite storm count
