Arcbound Reclaimer + Showdown of the Skalds + Mishra's Bauble + Mystic Forge

Arcbound Reclaimer

Showdown of the Skalds

Mishra's Bauble

Mystic Forge

How it works

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

This looping engine relies on Mystic Forge to let you cast Mishra's Bauble right off the top of your library for zero mana, immediately fueling Showdown of the Skalds's chapters to drop a +1/+1 counter onto Arcbound Reclaimer. You then sacrifice Mishra's Bauble to draw a card next turn, which triggers Arcbound Reclaimer's activated ability to spend that newly minted counter and recycle Mishra's Bauble right back to the top of your library. Repeating this loop endlessly racks up your storm count and triggers while feeding your graveyard, all powered by Mystic Forge's top-deck casting permissions.
