Temur Sabertooth + Gaea's Cradle + Great Oak Guardian + Forensic Researcher

Temur Sabertooth

Gaea's Cradle

Great Oak Guardian

Forensic Researcher

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 Forensic Researcher's first ability 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 Forensic Researcher any number of times.

This intricate engine relies on Temur Sabertooth to continuously bounce Great Oak Guardian back to your hand so it can be recast repeatedly. Each time Great Oak Guardian enters the battlefield, its triggered ability untaps your entire board, which includes not just your creatures but crucially Gaea's Cradle and Forensic Researcher as well. Tapping Gaea's Cradle fuels the mana required to recast the Guardian, while Forensic Researcher's tap ability provides an extra untap for your Cradle or other permanents to keep the loop self-sustaining. With enough creatures on the field, this dance generates infinite green mana, infinite storm count, and infinitely large creatures that you can blink indefinitely.
