Careful Cultivation + Umbral Mantle + Agatha of the Vile Cauldron
Infinite green manaInfinitely large creature until end of turnInfinite untap of creatures you controlInfinite mana creatures you control can produce
How it works
- Activate the creature with Careful Cultivation and Umbral Mantle attached by tapping it, adding .
- Activate the creature by paying at most 2 and untapping it, causing it to get +2/+2 until end of turn.
- Repeat.
- If Agatha of the Vile Cauldron has power 2 or greater, this combo nets infinite green mana.
This clever loop harnesses Umbral Mantle to repeatedly untap your creature while generating a massive surplus of mana. The secret lies in Agatha of the Vile Cauldron, whose static ability reduces the untap cost of the Mantle to just a single generic mana—allowing the tap ability provided by Careful Cultivation to net more mana than you spend to untap. As you cycle through tapping and untapping, the creature targeted by Careful Cultivation also grows infinitely large thanks to the continuous pumps from Umbral Mantle.
