Day of the Dragons

Demon of Fate's Design

Enchanted Evening

Cloudstone Curio

Trostani, Selesnya's Voice

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, Cloudstone Curio triggers that many times.
6. Resolve all but one Cloudstone Curio trigger, returning nothing to your hand from the battlefield.
7. Resolve the final Cloudstone Curio trigger, returning Day of the Dragons to your hand from the battlefield.
8. 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.
9. When the creatures that were exiled by Day of the Dragons enter the battlefield, Cloudstone Curio triggers that many times, and Trostani triggers for each creature except itself.
10. Resolve all Trostani triggers, causing you to gain life equal to the collective toughness of the other creatures that entered the battlefield.
11. Resolve all Cloudstone Curio triggers, returning nothing to your hand from the battlefield.
12. Repeat.
13. If creatures you control excluding Trostani have total base toughness 8 or greater, this combo nets infinite life.

This magnificent loop transforms the board into a recursive dragon-hatching engine, all fueled by Demon of Fate's Design letting you bypass the mana cost of Day of the Dragons by paying life instead. Enchanted Evening plays a quiet yet crucial role, turning every single permanent into an enchantment so that everything seamlessly shares types and triggers. Cloudstone Curio watches the chaos unfold, bouncing Day of the Dragons back to your hand the moment your new 5/5 Dragon tokens arrive. That bounce forces Day of the Dragons to leave the battlefield, which sacrifices the Dragons, brings your original creatures right back into play, and lets Trostani, Selesnya's Voice effortlessly harvest a massive wave of lifegain before you cast the enchantment all over again.
