Arcbound Reclaimer + Showdown of the Skalds + Tormod's Crypt + Gwenom, Remorseless

Arcbound Reclaimer

Showdown of the Skalds

Tormod's Crypt

Gwenom, Remorseless

How it works

1. Cast Tormod's Crypt either from your hand by paying 0 or from the top of your library by paying 0 life.
2. Showdown of the Skalds triggers, putting a +1/+1 counter on Arcbound Reclaimer.
3. Activate Tormod's Crypt by tapping and sacrificing it.
4. Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting Tormod's Crypt from your graveyard onto the top of your library.
5. Repeat.

This intricate loop harnesses the self-replenishing nature of Tormod's Crypt alongside the recycling prowess of Arcbound Reclaimer to endlessly loop zero-mana artifacts. Whenever you recast the Crypt, the chapters of Showdown of the Skalds feed a steady stream of +1/+1 counters back onto the Reclaimer to keep the activation cost paid. Meanwhile, Gwenom, Remorseless ties the engine together from the command zone or battlefield, letting you circumvent traditional mana costs to play cards directly from the top of your library by paying life instead.
