Isochron Scepter + Elder Druid + Roar of the Kha

Isochron Scepter

Elder Druid

Roar of the Kha

How it works

1. Activate any number of creatures you control by tapping them, adding at least 5.
2. Activate Isochron Scepter by paying 2 and tapping it, casting a copy of Roar of the Kha without paying its mana cost.
3. Resolve Roar of the Kha, untapping all creatures you control.
4. Activate Elder Druid by paying 3 and tapping it, untapping Isochron Scepter.
5. Repeat.

This clever loop centers on imprinting Roar of the Kha onto an Isochron Scepter, allowing you to repeatedly cast the entwined spell to untap your entire board for free. Elder Druid pulls its weight by serving as the dedicated untapper for the Scepter, consuming some of the mana your other creatures generate along the way. Because Roar of the Kha untaps all your creatures—including the Elder Druid itself—the whole system resets seamlessly. This yields an infinite cycle that pumps out endless mana, untaps, and magecraft triggers.
