How it works
Activate Wight of the Reliquary by tapping it and sacrificing another creature, causing you to search your library for a land card and put it onto the battlefield tapped.
When the land enters the battlefield, each Scute Swarm you control triggers.
Resolve the first trigger, creating either a 1/1 Insect creature token or a token copy of Scute Swarm.
When the creature token enters the battlefield, Intruder Alarm triggers, untapping all creatures.
Repeat from step 3 for each remaining trigger, if applicable.
Repeat from step 1.
This elegant engine transforms a single land drop into an overwhelming horde by letting Intruder Alarm turn every new arrival into a fresh untap for your entire board. With those untaps flowing freely, Wight of the Reliquary can repeatedly sacrifice disposable bodies to pull more lands straight from your library. Each new land immediately feeds Scute Swarm's landfall ability, which continuously pumps out fresh creatures to keep the Alarm ringing and the Wight working.
