How it works
Activate the Spider with Thornbite Staff and Hypervolt Grasp attached by tapping it, dealing 1 damage to a creature an opponent controls and destroying it due to the Spider's deathtouch.
When the creature dies, Shelob and the Spider tapped in step 1 trigger.
Resolve the Shelob trigger, creating a token copy of the creature that died that is a Food artifact.
Resolve the Spider trigger, untapping it.
Repeat as desired. You can also repeat this loop whenever a creature enters the battlefield under an opponent's control.
By outfitting any creature with both Thornbite Staff and Hypervolt Grasp, you grant it the ability to ping targets for 1 damage while creating an infinite loop of destruction. Because Shelob, Child of Ungoliant ensures that any creature damaged by your Spiders dies instantly thanks to deathtouch, the Staff's trigger immediately untaps your shooter to repeat the process. Meanwhile, Shelob's replacement effect capitalizes on this endless slaughter by turning every single casualty into a nourishing Food artifact under your control, locking down the opponent's board entirely.
