Temur Sabertooth + Gaea's Cradle + Great Oak Guardian + Tidewater Minion

Temur Sabertooth

Gaea's Cradle

Great Oak Guardian

Tidewater Minion

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 Tidewater Minion's second 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 Tidewater Minion any number of times.

This ingenious loop turns a massive board state into an endless engine of growth and mana, perfect for formats like Commander and Legacy. With Gaea's Cradle producing a torrent of green mana fueled by your wide board, Temur Sabertooth provides the repeatable bounce to return Great Oak Guardian to your hand after it enters. Recasting Great Oak Guardian triggers its ability to untap all your creatures—including Tidewater Minion, whose tap ability untaps Gaea's Cradle to keep the cycle going. Tidewater Minion also pairs with the untap triggers to reset itself, while the cascading buffs make your entire team infinitely large for the turn.
