Stone-Seeder Hierophant + Drownyard Temple + Dawn's Reflection + Squandered Resources

Stone-Seeder Hierophant

Drownyard Temple

Dawn's Reflection

Squandered Resources

How it works

1. Activate the land with Dawn's Reflection attached by tapping it, adding at least 1.
2. Dawn's Reflection triggers, adding two mana of any color(s).
3. Activate Stone-Seeder Hierophant by tapping it, untapping the land.
4. Activate Drownyard Temple by paying 3, returning it from your graveyard to the battlefield tapped.
5. When Drownyard Temple enters the battlefield, Stone-Seeder Hierophant triggers, untapping Stone-Seeder Hierophant.
6. Activate Squandered Resources by sacrificing Drownyard Temple, adding C.
7. Repeat.

This intricate engine transforms a single enchanted land into an absolute fountain of mana by exploiting the explosive mana-generation of Dawn's Reflection. Whenever you sacrifice Drownyard Temple to Squandered Resources for mana, you can immediately pay back into Drownyard Temple's own recursion ability to bring it right back from the graveyard. That recurring landfall triggers Stone-Seeder Hierophant, keeping its active untap ability ready to continuously refresh your primary land.
