Arcbound Reclaimer + Showdown of the Skalds + Welding Jar + Experimental Frenzy

Arcbound Reclaimer

Showdown of the Skalds

Welding Jar

Experimental Frenzy

How it works

1. Cast Welding Jar 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 top of your library into an endless recycling bin for **Welding Jar**, using **Experimental Frenzy** to let you cast the 0-mana artifact directly from the library without ever needing a hand. Every time **Welding Jar** is cast, chapters II and III of **Showdown of the Skalds** trigger, granting a +1/+1 counter to **Arcbound Reclaimer**. The **Arcbound Reclaimer** then spends that very counter to place the sacrificed **Welding Jar** right back on top of your library, perfectly setting up **Experimental Frenzy** to do it all over again.
