Temur Sabertooth + Gaea's Cradle + Great Oak Guardian + North Pole Patrol

Temur Sabertooth

Gaea's Cradle

Great Oak Guardian

North Pole Patrol

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 2.
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 North Pole Patrol by tapping it, untapping Gaea's Cradle.
6. Repeat.
7. Once you have infinite green mana, you 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 North Pole Patrol any number of times.

This clever loop generates infinite green mana by repeatedly bouncing and recasting Great Oak Guardian to leverage the massive mana production of Gaea's Cradle. Temur Sabertooth provides the essential bounce outlet to return the Guardian to your hand, while the untap triggers from Great Oak Guardian and North Pole Patrol ensure your lands and creatures stay fresh to keep the cycle going. As you repeat the process, North Pole Patrol also helps untap your resources and Temur Sabertooth keeps the Guardian safe with its indestructible ability, ultimately resulting in infinitely large creatures, infinite storm count, and endless mana.
