Reckoner Bankbuster + Coretapper + Ashnod's Altar + Thornbite Staff + Sculpting Steel

Reckoner Bankbuster

Coretapper

Ashnod's Altar

Thornbite Staff

Sculpting Steel

How it works

1. Activate Reckoner Bankbuster by paying 2, tapping it, and removing a charge counter from it, causing you to draw a card, create a Treasure artifact token and create a 1/1 Pilot creature token.
2. Activate Coretapper's first ability by tapping it, putting a charge counter on Reckoner Bankbuster.
3. Activate Ashnod's Altar by sacrificing the Pilot token, adding CC.
4. When the Pilot dies, Coretapper and Reckoner Bankbuster triggers, untapping themselves.
5. Repeat.

This intricate contraption turns Coretapper into an unstoppable charge-counter engine by looping its sacrifice and untap triggers through Thornbite Staff. As Coretapper feeds Ashnod's Altar with the Pilot token generated by Reckoner Bankbuster, the Staff's trigger neatly untaps both Coretapper and the Bankbuster so the whole cycle can begin anew. Meanwhile, Sculpting Steel sits ready to amplify your setup by copying whichever key piece your board state needs most, ensuring the draw-and-mana machine never runs dry.
