Temur Sabertooth + Gaea's Cradle + Great Oak Guardian + Stone-Seeder Hierophant

Temur Sabertooth

Gaea's Cradle

Great Oak Guardian

Stone-Seeder Hierophant

How it works

1. Activate Gaea's Cradle by tapping it, adding at least eight .
2. Activate Temur Sabertooth by paying 1, returning Great Oak Guardian to your hand.
3. Cast Great Oak Guardian by paying 5.
4. When Great Oak Guardian enters, it triggers itself, untapping all creatures you control and giving them +2/+2 until end of turn.
5. Activate Stone-Seeder Hierophant by tapping it, untapping Gaea's Cradle.
6. Repeat.
7. If you control nine or more creatures, this combo will net infinite green mana, which you then may activate Temur Sabertooth any number of times and recast any creatures castable with green mana any number of times, effectively "blinking" your green creatures any number of times.
8. You may also activate Stone-Seeder Hierophant any number of times.

This elegant loop relies on scaling your mana through Gaea's Cradle to continuously cycle Great Oak Guardian back to your hand with Temur Sabertooth and recast it. Each time Great Oak Guardian re-enters the battlefield, its triggered ability untaps your creatures and lands—including Stone-Seeder Hierophant, which in turn untaps Gaea's Cradle to keep the green mana flowing. As long as Gaea's Cradle produces enough mana to cover the casting cost and the bounce activation, Stone-Seeder Hierophant bridges the gap between your lands and creatures, allowing you to generate infinite mana, massive power boosts, and endless enters-the-battlefield triggers.
