How it works
Activate Cephalid Looter by tapping it, causing target opponent to loot.
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.
When the Orc Army enters the battlefield, Intruder Alarm triggers, untapping all creatures.
Activate Phyrexian Altar by sacrificing the Orc Army, adding one mana of any color.
Repeat.
This clever loop centers around Cephalid Looter's activated ability, which forces an opponent to draw and discard a card. That extra draw immediately awakens Orcish Bowmasters, whose triggered ability pings a target and creates a growing Orc Army token upon entry. Because that token is a creature entering the battlefield, Intruder Alarm triggers to untap all creatures, including our trusty Looter. Finally, Phyrexian Altar provides the means to sacrifice the newly minted Orc Army for colored mana, fueling the engine to repeat the whole sequence indefinitely.
