Decklist
I saw this deck on a lemmy-like social media platform that shall not be named, and fell in love with it. I think this is a really cool and tight package. The cards work together super well and you get to draw so many cards that it feels very consistent. I play [[Annihilating Glare]] instead of [[Lash of the Barlog]], but I'm otherwise mostly on board with the card choices (some minor substitions for cards I don't own, such as the artifact lands).
My local meta isn't super competitive (it's mostly just me and a friend who borrows my brews) so I haven't tested its mettle against really powerful decks, but it feels like it has game against a lot of decks. I've been toying with with the idea of using [[Dark Ritual]] to speed up the deck, which I think we could get away with since the deck draws so many cards and uses mostly black mana. I've also considered [[Crack the earth]] but I suppose that's more of a sideboard card against decks that play very few permanents such as turbo fog or something.
I think [[Reckoner's Bargain]] should be considered over [[Nasty End]] since sacrificing an artifact is much easier, but an extra card off the ring bearer is of course pretty sick. Not sure if one should play [[Lightning Bolt]] over [[Cast into the fire]]. That feels like a meta dependent choice. I feel that in my janky meta there is very often something you can kill with Cast into the fire, and it's worth it.
Cast into the Fire definitely feels like a meta call, being able to snipe artifact lands is nice but Bolt is so reliably good and depending on the number of artifacts you get out Galvanic Blast might be viable.
I think it's very unlikely to get metalcraft. Ichor wellsprings are usually sacrificed quite soon after you get them out (to [[Makeshift Munitions]], [[Annihilating glare]] or [[Deadly Dispute]]) and Myr Servitors don't always come in multiples and are easy to kill. I suppose with more artifact lands you could get there, but that leaves you much more vulnerable to artifact hate.
