Temur Sabertooth + Mana Reflection

Temur Sabertooth

Mana Reflection

How it works

1. Activate the mana-producing creature by tapping it, adding twice the usual amount of mana due to Mana Reflection.
2. Activate Temur Sabertooth by paying 1, returning the mana-producing creature from the battlefield to your hand and giving Temur Sabertooth indestructible until end of turn.
3. Cast the mana-producing creature by paying its mana cost.
4. Repeat any number of times.
5. If the loop produces infinite mana (see Notes), you can then spend that mana to activate Temur Sabertooth any number of times, returning and recasting any creatures you control whose costs can be paid for by the type of mana you have.
