Stone-Seeder Hierophant + Drownyard Temple + Gaea's Cradle + Zuran Orb

Stone-Seeder Hierophant

Drownyard Temple

Gaea's Cradle

Zuran Orb

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 Zuran Orb by sacrificing Drownyard Temple, causing you to gain 2 life.
6. Repeat.
7. If you control four or more creatures, this combo nets infinite mana.

This elegant loop hinges on Gaea's Cradle generating a massive surge of green mana, which fuels the recurring revival of Drownyard Temple from your graveyard. Along the way, Zuran Orb provides a reliable sacrifice outlet to bin the land while padding your life total. Meanwhile, Stone-Seeder Hierophant ties the whole mechanism together by acting as both a persistent untapper for Gaea's Cradle and a landfall trigger machine that resets itself every time the temple returns to the battlefield.
