Activate Tortured Existence by paying and discarding an artifact creature card, returning another artifact creature card from your graveyard to your hand.
Imotekh triggers, creating two 2/2 Necron Warrior artifact creature tokens.
When the Necron Warriors enter the battlefield, Blasting Station triggers twice, untapping Blasting Station.
Activate Blasting Station by tapping it and sacrificing a Necron Warrior.
When the Necron Warrior dies, Pitiless Plunderer triggers, creating a Treasure artifact token.
Resolve the Blasting Station ability, dealing 1 damage to any target.

This loop turns a simple graveyard swap into a relentless war machine by connecting recursive creature trading directly to artifact generation. When you use Tortured Existence to discard an artifact creature and retrieve another, Imotekh the Stormlord sees those cards leaving your graveyard and floods the board with Necron Warrior tokens. Each warrior's arrival untaps Blasting Station, letting you sacrifice the token to deal damage, which in turn triggers Pitiless Plunderer to leave behind a Treasure token. Sacrificing that Treasure provides the exact black mana needed to fuel Tortured Existence all over again, creating a self-sustaining cycle of death, damage, and rebirth.
