What must be in place

You control a creature with power 1 or greater that can attack and that cannot be blocked by an opponent.

How to execute it

1. Activate any number of lands by tapping them, adding at least {2}{R}{R}.
2. Cast Relentless Assault by paying {2}{R}{R}, causing you to untap all creatures that attacked this turn and causing you to get an additional combat and main phase after this one.

4. When the Timeless Witness token enters, it triggers, returning Relentless Assault from your graveyard to your hand.
5. Deal combat damage to an opponent. Nature's Will triggers, untapping all lands you control.
6. Move to your next main phase and repeat from step 1.
