Aggravated Assault + Bear Umbra

Aggravated Assault

Bear Umbra

How it works

1. Declare enchanted creature as attacker.
2. Bear Umbra triggers, untapping all lands you control.
3. Proceed to your next main phase.
4. Activate Aggravated Assault by paying 3, untapping all creatures you control and getting an additional combat and main phase after this one.
5. Repeat.

This classic synergy creates an infinite combat loop by turning your attack steps into a self-sustaining engine. When you send your creature enchanted by Bear Umbra into the red zone, its triggered ability untaps all your lands, immediately refunding the mana you need. You then head to your main phase and channel that recovered mana into Aggravated Assault, whose activation untaps your creatures and hands you an extra combat phase. By swinging again and repeating the cycle, you get infinite combat phases to overwhelm any opponent standing in your way.
