Anzrag, the Quake-Mole + Obscuring Haze + Forbidden Orchard + Argothian Elder

Anzrag, the Quake-Mole

Obscuring Haze

Forbidden Orchard

Argothian Elder

How it works

1. Activate Anzrag by paying 3, causing opponents to block Anzrag if able this turn.
2. Cast Obscuring Haze by paying 0 if you control a commander, or 2 otherwise, preventing all combat damage that would be dealt by opposing creatures this turn.
3. Declare Anzrag as an attacker, attacking any opponent.
4. If the opponent does not control a creature, activate Forbidden Orchard by tapping it, adding one mana of any color.
5. If Forbidden Orchard was activated, it triggers, causing the defending opponent to create a 1/1 Spirit creature token.
6. If Forbidden Orchard was activated, activate Argothian Elder by tapping it, untapping Forbidden Orchard.
7. The opponent is forced to block Anzrag, triggering Anzrag, untapping all creatures you control and causing you to get an additional combat phase after this one.
8. Any combat damage that would be dealt to Anzrag is prevented by Obscuring Haze.
9. Repeat from step 3 each combat phase.

This brilliant loop turns Anzrag, the Quake-Mole's forced-blocking mandate into an endless series of combats safely insulated by Obscuring Haze's damage prevention. By tapping Forbidden Orchard to generate mana and a token blocker, you give Anzrag a legal target to swing into while triggering Argothian Elder to untap the land. Argothian Elder can then untap itself as one of its two lands if you also tap a second land or cycle the untaps, allowing you to continually repeat the process while Anzrag survives unscathed and endlessly untaps your board for infinite combat phases.
