Halo Fountain + Vizier of Tumbling Sands + Illusionist's Bracers

Halo Fountain

Vizier of Tumbling Sands

Illusionist's Bracers

How it works

1. Activate a mana-producing permanent by tapping it, adding at least .
2. Activate Vizier of Tumbling Sands by tapping it, targeting Halo Fountain.
3. Illusionist's Bracers triggers, coping Vizier of Tumbling Sands' ability, targetting the mana-producing permanent.
4. Resolve both Vizier of Tumbling Sands abilities, untapping Halo Fountain and the mana-producing permanent.
5. Activate Halo Fountain's first ability by paying , tapping it and untapping Vizier of Tumbling Sands, creating a 1/1 Citizen creature token.
6. Repeat.

This clever loop relies on Illusionist's Bracers equipped to Vizier of Tumbling Sands, allowing its tap ability to trigger a copied activation that untaps both a mana source and Halo Fountain at the same time. As the Vizier untaps itself to Halo Fountain's first ability, you pump out an endless army of 1/1 Citizen tokens while generating infinite creature ETB triggers.
