Crucible of Worlds


You may play land cards from your graveyard.

Guerric on [Primer] Helming the Host of Heaven: A Giada Guide

I just wanted to respond to a few comments. Thanks for your patience!


True Conviction is a bit of a pet card for me, and I play it in a lot of decks, so its certainly a good suggestion. It's one of those cards that's always better than you expect it to be. The argument against it is that it is mana-intensive to cast and doesn't stick around too long as it is a target for removal. The weakness in this argument is that in decks where it is good you don't need it to stick around. As long as you can resolve it with a decent board, it will most of the time turn the course of the game and sometimes finish other players out of nowhere. It is a great card. I don't run it here because I have angels which do similar things. Sigarda's Vanguard, Lyra Dawnbringer, and Angelic Skirmisher do similar things while also being able to attack themselves and otherwise pump our team. In this deck we need as many angels as possible because we need to goldfish, and that limits our slots for enchantments that don't contribute to this theme. As such, I'm not playing it here, but those who are lacking some of the above angels may wish to. It's certainly good, I just feel in my case I need more synergy.

The Immortal Sun is, in my estimation, a pretty overrated card for most decks. It is at it's best as a hate card against super-friends decks which provides other benefits, so if that's a major thing in one's meta it is certainly worth considering. Aside from that, it does provide substantial benefits of course, serving as premium ramp, card draw, and an anthem to boot. That being said, doing too many things is not really an asset for a 6cmc card. It doesn't do any of these things at the point in the game where we need them (which is well before turn 6), and if we resolve it later, it will likely be removed before it can give us much benefit, leading to wasted turns. Compare that with True Conviction, which can immediately change the course of the game the turn it is cast, even if it is removed afterwards. I thought the card was cool when it first spoiled and I do have a former student who won a tournament because he used it to shut down and Atraxa player, but aside from cases where we are up against a powerful super-friends strategy and are fortunate enough to draw it, I think it just doesn't do enough at the time we need it to do the things it does.


You're welcome! Thanks for the kind words! You certainly can feel free to put fetch lands in. As you said, they would thin the deck. Even better would be to play lots of them with Crucible of Worlds and get all of your lands out! I just personally don't want to invest in fetch lands for that purpose in part because I don't want to spend the money on them and partly because philosophically I don't like playing off-color fetch lands in any deck, even though it currently still remains legal. That being said, if you want to, by all means do it! It will make the deck more powerful, particularly with Crucible.


I'm glad you are enjoying the deck! Too many lists for a deck like this tend to be good-stuff angels, or follow generic deckbuilding guidance that is misapplied here. Synergy is always the way to make a deck more powerful and consistent, and its actually even more important in aggressive decks than in control and combo decks.

In 1v1 I'm not sure this deck has ever lost. It's just very fast, and is hard for only a single opponent to keep under control. I had a colleague play it against me 1v1 while I piloted my best control-combo deck and I lost. As regards removal, if it's one specific deck you have in mind to destroy I can't comment with any authority without playing against that specific deck. I can give some general advice here, however, and that is that you don't want to play as much removal as you think you do. In general the pundits at the command zone would recommend somewhere around 10-12 pieces of targeted removal generally speaking, and by being in mono-white we have access to some of the best removal cards in the history of the game. This might lead us to believe that we should go all out here, but those same pundits would remind us that these are general guidelines don't apply to every deck, and that the deck's overall strategy needs to be weighed in. Though I am a control-combo player at heart I have built many successful aggressive decks here, and played elves pretty extensively in modern, and I can say that in good aggro decks we just can't afford to play too much removal. In order to win and remain viable we need to be able to goldfish very fast while also devoting a lot of space to hoarding cards and other resources to rebuild when we get blown out and play new threats when our current ones get removed. We just don't have the space to put in a lot of removal- if we make said space we'll run out of gas or options. Never forget that one of the best forms of removal is player removal. If we're worried about someone combo-ing off we'll kill them, and our other opponents will thank us for it. We also are happy to let them share some of the burden of removal. If someone is about to win with a combo and we don't have removal but an opponent does, they will certainly use it! We already are helping them out by having the target on our backs much of the time, so it is time for them to do their part. That's not to say that we won't remove things, and the best removal cards in white are indeed in this list! We just have to be willing to have a bit less than other decks since we have other means of dealing with opponents, and since we can't afford to sacrifice resources for more.

I think a little more land recursion would be a good idea, like Ramunap Excavator and The Mending of Dominaria. Crucible of Worlds is expensive, but good if you don't have a budget.

ElPared, I didn't really think of Crucible of Worlds, but I like my other 3 drops a little better. Usually the three lands from Life from the Loam are more than enough to close things out. I'll play around with crucible a bit, but my initial thought is to stick with Life from the Loam.

Soul Foundry seems a little expensive, but Sakura-Tribe Elder has some potential. I think the tradeoff for something like Explore or Growth Spiral is having a blocker at the expense of the cantrip. Which one is better might just depend on meta, but I'm definitely going to try out Sakura-Tribe Elder and see how it goes!

IHATENAMES, my usual Leyline of Sanctity plan is to remove it with Broken Bond or Force of Vigor from the board, or go wide/big with Scute Swarm or Tireless Tracker. That said, I really like the possibility of having other options as well. I can even see running a one-of Hall of Storm Giants in the main. Uro, Titan of Nature's Wrath is probably more of a sideboard card, but I think it would be pretty useful for changing the angle of the deck so it's not as all-or-nothing.

Thanks for the suggestions!

No problem :)

I thought of some other stuff if you're interested. Frst: Why Life from the Loam instead of Crucible of Worlds? If it's the $$$ cost, I totally get it, but if that's not the issue it seems like Crucible would benefit you more, unless I'm missing something.

You also might be able to take advantage of something like Soul Foundry to dupe your crabs. Nothing against the Illusion; it just seems like the cheap copies are too easy to kill is all. Depends on your meta I guess.

Lastly, I'm not sure what your early game looks like, but you might benefit from running Sakura-Tribe Elder as a cheap chump blocker/land fetcher early. Crabs are usually decent walls until like turn 4 or 5, though, so I imagine you don't need the extra defense that often, but SKE definitely has some utility in this deck as an expendable blocker when you can't afford to lose your crabs

Living Twister can take your deserts back to hand to replay them, Ruin Ghost can flicker them, Crucible of Worlds/Ramunap Excavator/Splendid Reclamation+Sylvan Safekeeper to return them from graveyard, Ancient Greenwarden to make more tokens per desert drop. Hour of Promise finally to be used as intended.

Maybe you can run more stuff to sac and return deserts to the battlefield to continually trigger Hazezon's Desertfall ability. You already got Crucible of Worlds, Ramunap Excavator, and Ancient Greenwarden for the continuous recursion, but what about stuff like Scapeshift, World Breaker, Squirrel Wrangler, Hammer of Purphoros, and Turntimber Sower?

The Hammer and the Wrangler also contribute to the token synergies, so there's that too.

If you really wanna be a bastard, just add some group hate land destruction that only you can benefit off of since you can always recur your lands more than your opponents.

Hey Andramalech! This looks like a fun build! I think it could be a little stronger if you dropped some of the traditional mill cards like Fractured Sanity and Fraying Sanity to power up and protect the crabs a bit more.

I think adding in Fastbond and/or Exploration would be really helpful for the extra lands at a low mana cost. Since you can only play 1 Fastbond you won't get it all the time, but I feel like it would be crazy if you land it (especially with Crucible of Worlds).

I'd definitely run some more of the traditional blue vintage cards as well like Brainstorm, Mental Misstep, Gitaxian Probe, and (budget allowing) Force of Will.

You mentioned Back to Basics in your write-up and I think that's a great inclusion. I like that you added Uro, Titan of Nature's Wrath as well, I can see that really helping out, especially if the game goes long!

Interesting build! +1

I could see Crucible of Worlds fitting well here. I use it to a pretty devastating effect in a Gruul Landfall deck that I've been toying with in private matches on Arena. Being able to repeat play sac-lands can really mount up your triggers, and I think what you already have here could benefit from some of that.

Take a peek here if you're interested in some more Landfall-oriented deviousness with Graveyard-Land mechanics: Gruul Landfall Arena Variant

Either way nice job!
