Agatha's Soul Cauldron + Ascendant Spirit + Devoted Druid + Primal Vigor
How it works
- Activate Ascendant Spirit using Devoted Druid's first ability by tapping it, adding .
- Activate Ascendant Spirit using Devoted Druid's second ability by putting a -1/-1 counter on it, untapping it.
- Repeat three additional times.
- Activate Ascendant Spirit's third ability by paying SSSS, putting four +1/+1 counters on it and causing it to gain the listed ability.
- Repeat until the number of instances of Ascendant Spirit's gained ability is equal to your deck size.
- Move to your combat phase, and deal combat damage to an opponent using Ascendant Spirit.
- Ascendant Spirit triggers once for each instance of the gained ability it has, causing you to draw that many cards.
This fascinating loop transforms ordinary mana generation into a massive draw engine by combining several distinct permanent-based advantages. With Agatha's Soul Cauldron exiling Devoted Druid and granting its abilities to Ascendant Spirit, your Ascendant Spirit gains the invaluable ability to tap for green mana and untap itself by placing a -1/-1 counter on it—a classic self-contained loop that generates infinite mana. Meanwhile, Primal Vigor supercharges your counters and token generation, though here its true power lies in doubling the +1/+1 counters placed during Ascendant Spirit's final level-up activation. By repeatedly pumping mana into Ascendant Spirit, you grow it into a powerhouse that triggers its combat damage draw ability an absurd number of times, letting you draw your entire deck in a single swing.
