Activate an Equipment's equip ability by paying 0, attaching it to any creature you control except Puresteel Paladin or the creature that has One with the Kami attached.
Activate Blasting Station by tapping it and sacrificing the creature with the Equipment attached.
When the creature dies, One with the Kami triggers, creating a number of 1/1 Spirit creature tokens equal to that creature's power.
When the Spirit(s) enter the battlefield, Blasting Station triggers that many times, untapping itself.
Resolve the Blasting Station ability from step 2, dealing 1 damage to any target.
Repeat.
This loop transforms the humble act of re-equipping gear into a devastating artillery strike, powered entirely by the synergy of three key permanents. With Puresteel Paladin granting free zero-mana equip costs via metalcraft, you can endlessly bounce an Equipment onto a sacrificial creature just to feed it to Blasting Station. The moment that creature hits the graveyard, One with the Kami steps in to reward you by flooding the board with a swarm of Spirit tokens based on the sacrifice's power. Those very same tokens entering the battlefield trigger Blasting Station to untap itself repeatedly, leaving you with infinite damage, creature sacrifices, and endless ETB triggers to clear the table.
