This is a combo deck involving Krak-clan Ironworks, Mishra, Artificer Prodigy and Furnace Celebration in combination with a bunch of small artifacts, ideally CMC 2 or less.

The overall plan is to use Krark-Clan Ironworks to sacrifice a small artifacts, allowing you to trigger, and pay for, Furnace Celebration over and over again. Mishra, Artificer Prodigy offers you both ramp and recursion for your small artifacts so you can, ideally, deal tons of damage while drawing tons of cards in the process.

Alternate win conditions: Empty the Warrens, Laboratory Maniac, Spine of Ish Sah
