Mox Opal Discussion

Mox Opal and Mox Diamond of course would make opening ramp more consistent and more explosive, but would be a pricey add if that's a concern. Jeweled Amulet is a bad mana rock, but it does do one thing well that is hard to come by outside of green colors: ramp you on turn 1. It's basically like a bad Llanowar Elf since you have to "reload" it, but it would also help early turn explosiveness in the games you draw it in your opener.

Ideally 4x Mox Opal would be played to reduce this problem. From my experience having 4x Springleaf Drum and 3x Spire of Industry I have not come across being unable to cast Master of Etherium . If this is a problem I might consider splashing some Island and removing some Mountain

I judge Moxen based on how capable they are in the early game, especially for casting Balan on Turn 3:

  • Mox Diamond requires a land to discard. It's the tamest downside of all of them. The first one I'd consider.
  • Chrome Mox requires a coloured card to imprint. Could exile something important more often than not. Distant second if I really wanted another Mox.
  • Mox Opal requires metalcraft. If I have an artifact-light opener, it can't do anything. Maybe better than Chrome.
  • Mox Amber requires a coloured Legend. This deck has a measly three in the 99, and only one of them could have it active early enough to matter. Worthless.
  • Mox Tantalite requires being suspended. It comes off suspend on Turn 4 at the earliest, and becomes a dead draw very quick. Hot garbage.

Fatal Push, Underground River, and Mental Misstep are under $5 dollars, so I'm not going to give replacements on those, but for Ancient Tomb , City of Traitors , Glimmervoid , Inkmoth Nexus , Mox Opal , and Mox Diamond , I'd replace those with 3 Islands and a Swamp and add a River of Tears and Spire of Industry .

BTW, did you mean Underground Sea when you typed Underground River ? In which case I'd add Underground River over Underground Sea anyway.

For Force of Will , I'd use Steel Sabotage , it acts as an occasional counter and protection for your artifacts if you bounce them in response to removal, or to reuse them in case of Renaming a new card with Revoker or getting another cast trigger on Sai, etc.

Spellskite is harder, for this Lightning Greaves would be my pick, but Swiftfoot Boots additionally works for budgetary reasons.

Arcbound Ravager is the hardest. Any other artifact based finisher you'd like can work, but Mirrodin Besieged is my favorite.

Sorry, allow me to clarify; I have most of the deck, minus some of the more expensive pieces, specifically:

Ancient Tomb Arcbound Ravager City of Traitors Fatal Push Force of Will Glimmervoid Inkmoth Nexus Lotus Petal Mental Misstep Mox Diamond Mox Opal Spellskite Underground River

Those are the ones I know off of memory that aren't in my collection, or are above 5$ that I don't have. Steel Overseer getting reprinted makes it easier to get a hold of it.

It depends on what you're trying to achieve. I've taken most of the tutors out ( Planar Portal and Planar Bridge fit the theme), and am trying to eliminate any infinite combos. Some cards like Lux Cannon are in for flavor, since every mad scientist needs a ray gun...

If you want max power I think you use Mox Opal and Grim Monolith for faster starts as well. Jin-Gitaxias, Core Augur fits a purely cutthroat meta (it's too oppressive otherwise).

The five cards in my maybe board will be replacing Brainstorm , Basilisk Collar , Rings of Brighthearth , Clock of Omens , and Unsubstantiate . Endbringer is also too mana intensive and Urza needs a mount, so Nezahal, Primal Tide will replace it. Hope that helps.

"not sure why people keep mentioning Ancient Stirrings . they can leave Faithless Looting alone as well. too many other decks depend on it."

Faithless Looting is the exact kind of card you want to ban BECAUSE so many decks depend on it. Its an extremely cheap and efficient way to move 4 cards into zones where you can use them better, which means any deck that has value from the graveyard and can splash red wants to run it. 56 card format with faithless looting as an option.

Ancient Stirrings is far more degenerate than Preordain . Digging 5 deep for 1 mana is absurd, and seeing as most decks are about 1/3 lands it is extremely rare to whiff. Decks that run this bad boy are built to have it read " for the best card in your top five" which is pretty strong for 1 mana.

Here's what I'd love to see ideally for the B&R
