• Deserted Temple
• Rings of Brighthearth

What must be in place

You have at least one nonland card in hand.

How to execute it

1. Activate Deserted Temple's second ability by paying {0} due to Blossoming Tortoise and tapping it, targeting itself.
2. Rings of Brighthearth triggers, causing you to pay {2} to copy Deserted Temple's ability, targeting Deserted Temple.
3. Resolve the copy of Deserted Temple's ability, untapping it.
4. Activate Deserted Temple by tapping it, adding two mana of any color and causing the next spell you cast this turn to have cascade.
5. Resolve the Deserted Temple ability from step 1, untapping it.
6. Repeat.
7. Cast any nonland card from your hand by paying its mana cost, causing you to get infinite cascade triggers based off the mana value of that spell.

What the combo produces

• Infinite cascade with mana value equal to the next spell you cast
