Activate Blasting Station by tapping it and sacrificing any other creature.
When the creature dies as a Cleric due to Xenograft, Rotlung Reanimator triggers, creating a 2/2 Zombie creature token.
When the Zombie enters, Blasting Station triggers, untapping Blasting Station.
Resolve the Blasting Station ability from step 1.
Repeat.
This loop transforms any disposable creature into a lethal engine by rewriting the rules of the battlefield. Xenograft is the linchpin here, turning every creature you control into a Cleric so that Rotlung Reanimator can step in whenever one dies to immediately replace it with a 2/2 Zombie token. That fresh arrival triggers Blasting Station, untapping it so you can sacrifice the new Zombie to deal another point of damage and start the cycle all over again.
