Stone-Seeder Hierophant + Drownyard Temple + Serra's Sanctum + Overgrown Estate

Stone-Seeder Hierophant

Drownyard Temple

Serra's Sanctum

Overgrown Estate

How it works

1. Activate Serra's Sanctum by tapping it, adding at least .
2. Activate Stone-Seeder Hierophant by tapping it, untapping Serra's Sanctum.
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 enchantments, this combo nets infinite mana.

This loop turns the enchantment-scaling mana of Serra's Sanctum into an engine of endless rebirth and profit, provided you have at least four enchantments to fuel the math. By using Overgrown Estate, you feed Drownyard Temple to the graveyard, only to immediately pull it back into play using the generated white mana. Every time that Drownyard Temple enters the battlefield, Stone-Seeder Hierophant's landfall ability untaps the Hierophant itself—while its activated ability keeps Serra's Sanctum perpetually fresh for tapping—creating a self-sustaining cycle of land sacrifice and return that nets infinite life and white mana.
