How it works
Activate Magar by paying 1, noting Savage Beating and putting it face down as a 3/3 creature.
On any other turn, deal combat damage to an opponent with the face down creature.
The face down creature triggers, causing you to cast a copy of Savage Beating without paying its mana cost.
Resolve the copy of Savage Beating, causing you to untap all creatures you control and to get an additional combat phase after this one.
