Arcbound Reclaimer + Showdown of the Skalds + One with the Multiverse + Welding Jar

Arcbound Reclaimer

Showdown of the Skalds

One with the Multiverse

Welding Jar

How it works

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

This clever loop turns the zero-mana artifact Welding Jar into an infinitely recastable engine, fueled by the top-deck freedom granted by One with the Multiverse. Showdown of the Skalds acts as the crucial bridge for the combo, turning each cast into a fresh +1/+1 counter on Arcbound Reclaimer. Every time you sacrifice Welding Jar to protect an asset, Arcbound Reclaimer happily consumes that newly gifted counter to recycle the Jar right back onto the top of your library for free casting.
