Arcbound Reclaimer + Iron Spider, Stark Upgrade + Krark-Clan Ironworks + Sol Ring + Inexorable Tide

Arcbound Reclaimer

Iron Spider, Stark Upgrade

Krark-Clan Ironworks

Sol Ring

Inexorable Tide

How it works

1. Cast Sol Ring by paying its mana cost.
2. When you cast that spell, Inexorable Tide triggers, putting one +1/+1 counter on Arcbound Reclaimer and at least two additional artifacts you control.
3. Activate Sol Ring by tapping it, adding mana.
4. Activate Krark-Clan Ironworks by sacrificing Sol Ring, adding CC.
5. Activate Arcbound Reclaimer by removing a +1/+1 counter from it, putting Sol Ring from your graveyard on top of your library.
6. Activate Iron Spider's last ability by paying 2 and removing two +1/+1 counters from artifacts you control, drawing Sol Ring.
7. Repeat.

This fascinating loop transforms the modest recycling ability of Arcbound Reclaimer into a powerful engine by feeding artifacts directly back into your hand. By sacrificing Sol Ring to Krark-Clan Ironworks for mana, you send the ring to the graveyard so Arcbound Reclaimer can place it right back on top of your library using one of its +1/+1 counters. Iron Spider, Stark Upgrade then steps in to convert your accumulated counters into card draw, allowing you to easily redraw Sol Ring and cast it all over again. Along the way, Inexorable Tide effortlessly keeps your counter economy flowing by proliferating whenever you cast a spell, ensuring you never run out of the resources needed to sustain the loop.
