Oblivion Ring + Detention Sphere + Archon of Sun's Grace + Copy Enchantment

Oblivion Ring

Detention Sphere

Archon of Sun's Grace

Copy Enchantment

How it works

1. Cast Copy Enchantment by paying 2, causing it to enter the battlefield as a copy of Oblivion Ring.
2. When Copy Enchantment enters the battlefield, its first ability and Archon of Sun's Grace trigger.
3. Resolve the Archon of Sun's Grace trigger, creating a 2/2 Pegasus creature token.
4. Resolve the Copy Enchantment trigger, exiling Oblivion Ring.
5. When Oblivion Ring leaves the battlefield, its second ability triggers, returning Detention Sphere from exile to the battlefield.
6. When Detention Sphere enters the battlefield, its first ability and Archon of Sun's Grace trigger.
7. Resolve the Archon of Sun's Grace trigger, creating a 2/2 Pegasus creature token.
8. Resolve the Detention Sphere trigger, exiling Copy Enchantment.
9. When Copy Enchantment leaves the battlefield, its second ability triggers, returning Oblivion Ring from exile to the battlefield.
10. When Oblivion Ring enters the battlefield, its first ability and Archon of Sun's Grace trigger.
11. Resolve the Archon of Sun's Grace trigger, creating a 2/2 Pegasus creature token.
12. Resolve the Oblivion Ring trigger, exiling Detention Sphere.
13. When Detention Sphere leaves the battlefield, its second ability triggers, returning Copy Enchantment from exile to the battlefield as a copy of Oblivion Ring.
14. Repeat from step 2.

This mesmerizing loop sets up a perpetual motion machine between your enchantments by leveraging their entering and leaving triggers to endlessly catch and release each other. As Oblivion Ring and Detention Sphere continuously trade places in exile—with Copy Enchantment cleverly mimicking the former—they never truly disappear from the battlefield for good. Meanwhile, Archon of Sun's Grace stands by as your tireless engine, its constellation ability feeding on every single cycle to rain down an endless flock of flying Pegasus tokens.
