Arcbound Reclaimer + Showdown of the Skalds + Urza's Bauble + One with the Multiverse

Arcbound Reclaimer

Showdown of the Skalds

Urza's Bauble

One with the Multiverse

How it works

1. Cast Urza's Bauble 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 Urza's Bauble by tapping and sacrificing it.
4. Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting Urza's Bauble from your graveyard onto the top of your library.
5. Repeat.

This loop turns a seemingly innocuous trinket into an engine of endless repetition, all anchored by One with the Multiverse letting you effortlessly replay Urza's Bauble from the top of your library for zero mana. Each time you cast that artifact, Showdown of the Skalds triggers to replenish Arcbound Reclaimer with the precise +1/+1 counter it needs to fuel its activated ability. By spending that counter to place Urza's Bauble right back onto your library, you create a seamless recycling loop that generates infinite artifact triggers, sacrifice events, and delayed card draw.
