Day of the Dragons + Demon of Fate's Design + Enchanted Evening + Cloudstone Curio + Ajani's Welcome

Day of the Dragons

Demon of Fate's Design

Enchanted Evening

Cloudstone Curio

Ajani's Welcome

How it works

1. Cast Day of the Dragons by paying 7 life due to Demon of Fate's Design.
2. When Day of the Dragons enters the battlefield, its first ability and Cloudstone Curio trigger.
3. Resolve the Cloudstone Curio trigger, returning nothing to your hand from the battlefield.
4. Resolve the Day of the Dragons trigger, exiling all creatures you control and creating that many 5/5 Dragon creature tokens.
5. When the Dragon(s) enter the battlefield, Ajani's Welcome and Cloudstone Curio trigger that many times.
6. Resolve all Ajani's Welcome triggers, causing you to gain 1 life for each Dragon that entered the battlefield.
7. Resolve all but one Cloudstone Curio trigger, returning nothing to your hand from the battlefield.
8. Resolve the final Cloudstone Curio trigger, returning Day of the Dragons to your hand from the battlefield.
9. When Day of the Dragons leaves the battlefield, its second ability triggers, causing you to sacrifice all Dragons you control and return all cards exiled with Day of the Dragons to the battlefield.
10. When Demon of Fate's Design and any other creature(s) that were exiled by Day of the Dragons enter the battlefield, Ajani's Welcome and Cloudstone Curio trigger that many times.
11. Resolve all Ajani's Welcome triggers, causing you to gain 1 life for each creature that entered the battlefield.
12. Resolve all Cloudstone Curio triggers, returning nothing to your hand from the battlefield.
13. Repeat.

This delightfully intricate loop transforms your entire battlefield into a recursive engine, starting with Demon of Fate's Design allowing you to bypass the mana cost of Day of the Dragons by paying life instead. Meanwhile, Enchanted Evening weaves everything together by turning all permanents into enchantments, ensuring that your creatures and tokens seamlessly satisfy Cloudstone Curio's type-matching bounce requirements. As your creatures cycle in and out of exile, Ajani's Welcome cushions the life payment by constantly refunding your health, turning a catastrophic dragon transformation into an endless cascade of enters-and-leaves-the-battlefield triggers.
