Absurd New Common Enables Wild Gamebreaking Infinite Combos

Teenage Mutant Ninja Turtles has introduced a new Goblin Welder infinite combo with Sewer-veillance Cam, a cheap artifact with the impactful ability to tap or untap a creature when it enters or leaves play. The combination goes infinite, making it perfect to upgrade that Tawnos, Urza's Apprentice deck collecting dust in the closet.

Understanding the Combo

This is one of the simplest artifact combos you can run. You need to control Goblin Welder and Sewer-veillance Cam, plus have an artifact in your graveyard—Mishra's Bauble, for example. You also need to be able to activate Goblin Welder.

Tap the Welder, sacrificing SVC and targeting Mishra’s Bauble. This triggers SVC’s leave the battlefield trigger, which untaps Goblin Welder. You then sacrifice the Bauble to Welder to reanimate Sewer-veillance Cam; when it enters, it untaps Welder to start the loop over.

This results in infinite leaves the graveyard triggers, plus infinite artifact entering triggers and artifact sacrificing triggers. If the spare artifact in question was an artifact creature, you also get infinite creaturefall and death triggers.

Part of this combo’s charm is its extremely low cost. The above example costs , which is hard rate to beat for an infinite combo. In theory, it could cost even less; the combo can start with Sewer-veillance Cam in the graveyard if you have an artifact, so you could theoretically start from with the Welder. I also appreciate that both pieces of the combo can be tutored up with Dizzy Spell’s transmute ability. Both cards also have ample applications outside the combo, which means you’ll never have half the combo rotting in your hand.

It’s not without weaknesses, however. Goblin Welder is extremely fragile and telegraphed, since it needs to survive a turn cycle to activate unless you have a haste enabler. The combo itself also doesn’t win; you need another piece, even if it’s just a specific artifact.

Turning It Into a Win

The easiest way to turn the Welder-Cam into a win is by choosing a specific third artifact. Mishra's Bauble is nice and all since it costs and sacrifices itself, but it doesn’t make the graveyard looping into a win. Picking an artifact with a good enters/leaves trigger can, however.

Fireforger's Puzzleknot, Perilous Myr, and Mortarpod all turn the loop into infinite damage—though Mortarpod requires sacrificing the token it creates before you sacrifice them. Those aren’t the only options for this effect, just the cheapest. These produce a quick win, but can water your deck down with cards that only matter if you’re comboing. If you don’t pick an artifact that automatically wins, you can add an additional card.

Cards like Reckless Fireweaver, Disciple of the Vault, and Hedron Detonator trigger infinitely as the artifacts recur (this technically triggers cards like Teval, the Balanced Scale, but those effects are mostly Sultai () that they seem unlikely to help).

An upside to using these over, say, the Puzzleknot is that they work with multiple different combos and can even win the game fairly if you have a B plan (or the combo is your B plan). Also, if your artifact of choice is an artifact creature, Blood Artist effects work here, too.

You could also establish loops that don’t involve damage. Artifacts that draw cards when they enter/die like Cryogen Relic and Solemn Simulacrum draw your deck, either to find one of the above finishers or set up a different win with Thassa's Oracle. You could also just loop a great enters trigger, like Meteor Golem to remove nonland permanents, though that option is weaker than the others.

Other Applications for Sewer-veillance Cam

Goblin Welder is the most efficient combo with Sewer-veillanc Cam, but it’s not the only one, and it’s worth highlighting extra combos that add additional lines to your decks.

SVC goes infinite with Emry, Lurker of the Loch so long as you have an artifact sacrifice outlet and a way to pay ; Urza, Lord High Artificer and Krark-Clan Ironworks are good choices. Another option could be Displacer Kitten and Lotus Petal.

SVC also works nicely with dorks that tap for multiple mana, like Bloom Tender. It can just be a ritual if the dork taps for more mana than SVC costs, or you could make a mana generation engine by flickering it with Displacer Kitten. Though small, SVC’s powerful untap ability offers a variety of uses as a combo piece or way to abuse unfair activated abilities.
