Karn, Silver Golem animates The One Ring for 1 mana; tapping it draws cards equal to its burden counters, then Skirge Familiar converts two of those drawn cards into the 2 mana Voltaic Construct needs to untap it and repeat. The combo lives in colorless-and-black artifact shells — Karn as commander is the obvious home, and every piece except Skirge Familiar pulls double duty as general artifact utility.

Recipe

How it works

Prerequisites

The One Ring has at least two burden counters on it and does not have summoning sickness.

Steps

Activate Karn by paying , causing The One Ring to become an artifact creature until end of turn.
Activate The One Ring by tapping it, putting a burden counter on it and causing you to draw a card for each burden counter on it.
Activate Skirge Familiar twice by discarding two cards, adding .
Activate Voltaic Construct by paying , untapping The One Ring.
Repeat from step 2.

Result

Infinite draw triggers; Near-infinite black mana; Near-infinite card draw; Near-infinite looting; Near-infinite self-discard triggers

Variations

Cheaper, tighter, alternate lines

The loop requires at least two burden counters before it becomes self-sustaining — the ring enters with zero, so it needs two prior tap activations before this line goes infinite. Umbral Mantle is a one-card replacement for Voltaic Construct if artifact-creature untapping is already in the build, saving a slot. Black mana generated by Skirge Familiar closes the game with Exsanguinate or Torment of Hailfire; otherwise the draw alone empties the library into a Thassa's Oracle or Laboratory Maniac kill.
