Sword of Feast and Famine + Aggravated Assault

Sword of Feast and Famine

Aggravated Assault

How it works

1. Deal combat damage to an opponent with the creature that has Sword of Feast and Famine attached.
2. Sword of Feast and Famine triggers, causing that opponent to discard a card, and you to untap all lands you control.
3. Proceed to your postcombat main phase.
4. Activate all mana producing lands you control by tapping them, adding at least 3.
5. Activate Aggravated Assault by paying 3, untapping all creatures you control and causing you to get an additional combat and main phase after this phase.
6. Repeat.
