How it works
Activate Gaea's Cradle by tapping it, adding at least eight .
Activate Temur Sabertooth by paying 1, returning Great Oak Guardian to your hand.
Cast Great Oak Guardian by paying 5.
When Great Oak Guardian enters, it triggers itself, untapping all creatures you control and giving them +2/+2 until end of turn.
Activate Fatestitcher by tapping it, untapping Gaea's Cradle.
Repeat.
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.
You may also activate Fatestitcher any number of times.
This brilliant engine turns a wide board into an unstoppable cascade of mana and triggers, perfectly anchored by Gaea's Cradle producing an abundance of green mana with each tap. Temur Sabertooth serves as the repeatable recall mechanism, paying its cost to bounce Great Oak Guardian back to your hand so it can be recast with flash and pump your team. Every time Great Oak Guardian re-enters the battlefield, its triggered ability untaps both your lands and your creatures, which in turn refreshes Gaea's Cradle and untaps Fatestitcher to repeat the cycle.
