Deceiver Exarch + Displace + Archaeomancer + Chromatic Orrery

Deceiver Exarch

Displace

Archaeomancer

Chromatic Orrery

How it works

1. Activate Chromatic Orrery's first ability by tapping it, adding 5.
2. Cast Displace by paying 3, blinking Archaeomancer and Deceiver Exarch.
3. Archaeomancer and Deceiver Exarch enter the battlefield, triggering their abilities.
4. Resolve the Archaeomancer trigger, returning Displace from your graveyard to your hand.
5. Resolve the Deceiver Exarch trigger, untapping Gilded Lotus.
6. Repeat.
7. Once you have infinite mana, you may instead activate Chromatic Orrery's second ability to draw infinite cards.
