Stone-Seeder Hierophant + Drownyard Temple + Gaea's Cradle + Overgrown Estate

Stone-Seeder Hierophant

Drownyard Temple

Gaea's Cradle

Overgrown Estate

How it works

1. Activate Gaea's Cradle by tapping it, adding at least .
2. Activate Stone-Seeder Hierophant by tapping it, untapping Gaea's Cradle.
3. Activate Drownyard Temple by paying 3, returning it from your graveyard to the battlefield tapped.
4. When Drownyard Temple enters the battlefield, Stone-Seeder Hierophant triggers, untapping Stone-Seeder Hierophant.
5. Activate Overgrown Estate by sacrificing Drownyard Temple, causing you to gain 3 life.
6. Repeat.
7. If you control four or more creatures, this combo nets infinite mana.

This elegant loop turns a modest board state into a boundless engine by exploiting the explosive mana production of Gaea's Cradle, which easily surpasses the activation costs required to keep the cycle going when you control four or more creatures. By utilizing Overgrown Estate as a reliable sacrifice outlet, you send Drownyard Temple straight to the graveyard so it can be brought right back to the battlefield for a modest mana investment. That recurring landfall trigger immediately awakens Stone-Seeder Hierophant, whose tap ability ensures Gaea's Cradle stays fresh and ready to flood your mana pool anew.
