Focuses around one card: Goblin Welder. Idea is to bounce your free/1 cost artifacts with Goblin Welder and put in your giant artifacts from the graveyard into play for free.
Free/1 drop bounce artifacts:
Great Furnace is an artifact land so you’ll have an artifact easily on standby in order bounce. With 2 being the most expensive thing your gonna play, you really don’t need a lot of lands.
Lotus Petal is free ramp. Not much to say, play it to get your combo out sooner early game or bounce it if needed late game.
Implement of Combustion gives card draw when bounce so it is the best artifact to sac.
Big boys:
Wurmcoil Engine is the main guy your going to be bringing back, 6/6 deathtouch lifelink? Yes please. But wait there’s more! You can bounce him for something else and you will get two more artifacts and then can rebounce Wurmcoil Engine back again. He does it all, only $20.99 (plus shipping and handling).
Combustible Gearhulk is a massive card draw engine (funny as he is the only non-engine in the 3 creatures). Your opponent has to pick between two terrible choices: either let you refill your hand or take a bunch of burn damage. And you can and will do this multiple times so the choice gets harder and harder as time rolls.
Now about burn... every time you bounce Scuttling Doom Engine your opponent takes 6 burn damage. This adds up REALLY quickly.
Mindslaver is the janky infinite lockout win condition. You just force your opponent to waste all their cards, kill their own board, and tap all their land each turn since you can use this every turn. Once you get one off you just win.
Setup:
Lightning Bolt needs no explanation...
Faithless Looting, Cathartic Reunion, and Burning Inquiry all cycle through your deck, draw you a bunch of cards, and fills up your graveyard in order to do Welder combos.
Noxious Revival is a tech card. Mainly it’s a failsafe/redundancy in case you discard a bunch of your Goblin Welder or a lot of them die/get countered. The deck doesn’t work without the Welder so it’s really important to get him out and to keep him alive.
Lands:
Bloodstained Mire and Wooded Foothills are fetchers to thin out your deck (very important to get better draws and the life loss does not matter).
Great Furnace is an artifact land. It activates everything you need so run 4.
That’s it. If you like the deck upvote it and try the deck out. If any one has ideas for improvements please comment, always open for help. Still need to figure out a sideboard that would fit so if anyone has ideas on this would be very much appreciated. Built this playing against the Elves v Inventors dual decks and loving the Goblin Welder inventors deck... plus the meme my friend group made of going “full Welder”. Fun Fact: I made this originally as a modern deck until I found out Goblin Welder isn’t allowed there. So I had to make a few adjustments. Doesn’t change the core gist but I found it funny.
