Temur Sabertooth + Gaea's Cradle + Hyrax Tower Scout + Forensic Researcher

Temur Sabertooth

Gaea's Cradle

Hyrax Tower Scout

Forensic Researcher

How it works

1. Activate Gaea's Cradle by tapping it, adding at least six .
2. Activate Temur Sabertooth by paying 1, returning Hyrax Tower Scout to your hand.
3. Cast Hyrax Tower Scout by paying 2.
4. When Hyrax Tower Scout enters, it triggers itself, untapping Forensic Researcher.
5. Activate Forensic Researcher 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 Forensic Researcher any number of times.

This elegant loop relies on Hyrax Tower Scout entering the battlefield to continuously untap Forensic Researcher, which in turn refreshes Gaea's Cradle to flood your pool with an abundance of green mana. With that surplus of mana fueling Temur Sabertooth, you can comfortably bounce the scouting scout right back to your hand and recast it to restart the cycle. Forensic Researcher's presence is doubly rewarding here, as its tap ability doesn't just untap your legendary land, but also offers the utility to tap down opposing threats when you collect evidence.
