Orcish Bowmasters + Intruder Alarm + Lumengrid Augur + Phyrexian Altar

Orcish Bowmasters

Intruder Alarm

Lumengrid Augur

Phyrexian Altar

How it works

1. Activate Lumengrid Augur by paying 1 and tapping it, causing target opponent to loot.
2. Orcish Bowmasters triggers, dealing 1 damage to any target, then creating a 0/0 Orc Army creature token and putting a +1/+1 counter on it.
3. When the Orc Army enters the battlefield, Intruder Alarm triggers, untapping all creatures.
4. Activate Phyrexian Altar by sacrificing the Orc Army, adding one mana of any color.
5. Repeat.

This loop turns the simple loot of Lumengrid Augur into a devastating engine by turning every opponent's draw into a weapon. Each time Lumengrid Augur forces a player to draw, Orcish Bowmasters triggers to deal damage and spawn an Orc Army token, which immediately wakes up the entire board—including Lumengrid Augur itself—thanks to Intruder Alarm's static untap ability. Sacrificing that freshly made token to Phyrexian Altar provides the mana needed to keep activating Lumengrid Augur over and over, all while slowly burning your opponents down to ash.
