trippy_mcfly on Cumly Cube

4 months ago

Introducing Cumly Cube 1.3! Two years ago, Cumly Cube was updated to Cumly Cube 1.2, creating a balanced cube and wonderful play experience for all involved. Despite these changes, there remained some minor flaws in the card pool. I am now pleased to announce that, after extensive research and design, Cumly Cube has reached a final form. No card is too powerful. No card is too weak. Synergy is abundant. Both the draft and play experiences are dynamic, exciting, and new. There will be no more major updates to Cumly Cube 1.

120 cards have been removed, and 120 cards have been added. Here are the changes, provided with brief justifications:

In deck building situations like this I always try to sneak in a stax tax that's irrelevant to the strategy. Your deck is artifact free but your opponents will be relying on them. Exploit that :)

Null Rod & Stony Silence

markbeloit on Kura

1 year ago

You wrote me an essay Profet93, so I took awhile to respond. Will try and address your question comments one-by-one.

Regarding Null Rod: It was in the prototype of this deck, but Collector Ouphe was cheaper, so I opted for the ouphe.

Regarding Snow-Covered Forests: Would probably be better, but I'd rather not pay the $.

Regarding Elemental Bond/Garruk's Uprising vs Colossal Majesty: In 90% of decks I'd agree with you that those two are better, but in this deck, I think Colossal Majesty might be better. I don't have that many creatures ETBing, and sometimes I have a big creature around for several turns. In those scenarios, I think Colossal Majesty generates more value.

Regarding Hour of Promise: Good, but not sure I need it.

Regarding Pir's Whim: Good, and not a card I knew of. Will have to keep an eye out for something to cut.

Regarding Yavimaya Hollow: Too much $. I don't think I need it enough.

Regarding Miren, the Moaning Well: I don't like Miren very much. True it's a second sac outlet, but I consider it vastly inferior to High Market. I really don't like having to pay {3}. And while I'm in trouble if someone blows up High Market, that hasn't happened yet.

Regarding Castle Garenbrig: Should probably cut a forest for this, and probably will when I get one.

Regarding Mirrorpool: Worth considering. There's only a few instants and sorceries I'd want to sac a land to copy, though, and I have to pay {2}{C}. Also, I'm trying to be a bit careful about how many utility lands I have in the deck, specifically lands that don't make {G}. If you have too many colorless lands you can get screwed.

Regarding Greater Good: Was a card I was seriously considering when building the deck, but saccing Kura to it is not that great. Bottom line, though, I thought for sure Greater Good would get destroyed immediately if I played it, which is why I decided against it.

Regarding Nylea's Intervention: Ok, but not sure I need it.

As always, a problem is what to cut. This deck does fairly well, and when that's the case, I'm always leery of cutting a card unless I see something strictly better.

Regarding Abundance + Sylvan Library: Drawing 3 cards per turn with no down side is fine, though it doesn't happen often :)

Regarding Abundance, it actually has some additional tech to it. In this deck I've been able to put every land in my deck into play once or twice. With Abundance, you put the revealed cards you don't get on the bottom of your library in ANY order, not a random order. So if I Abundance to get a land and don't have any in my deck.... I can rig the order of my deck. At that point your basically tutoring instead of drawing. Doesn't happen often, but is powerful when it does.

You also can't deck yourself if Abundance is in play, though that hasn't come up yet. A fun piece of tech, though not for every deck.

Sorry for taking so long to respond. I put it off since I knew I'd have to write a lot. Thanks for the suggestions, and I'll think of them, though again the problem is what to cut.

Your best bet imho is to try and prevent activations with cards like Pithing Needle Cursed Totem Interdict Null Rod Phyrexian Revoker Sorcerous Spyglass Damping Matrix or Karn, the Great Creator

Some things will still fly under the radar tho and does not really help your Sauron I guess.

SufferFromEDHD on Land, ho!

Overburden > Crystal Shard

Do you need the equipment? Damping Matrix, Null Rod and Collector Ouphe would do serious work in this strategy.

Floodbringer and Oboro Breezecaller value.

I like your fight + stax pieces. Have you thought of adding redundancy for collector ouphe with Null Rod or do you believe it's not necessary? It only shuts off the activated ability of conduit of worlds.

You should swap out half of your forests for snow-covered to trigger field of the dead more easily.

Elemental Bond/Garruk's Uprising > Collasal majesty.

Hour of Promise - Land tutor

Pir's Whim - Land tutor + politics and/or removal.

Yavimaya Hollow - Protection + politics. I get you want stuff to die most of the time but it's nice to be able to protect something or be political when you want to.

Mirrorpool - Copy important instants and sorceries

Miren, the Moaning Well - Sac outlet for commander. can also sac the token it makes to gain life in a pinch.

Castle Garenbrig - Ramp

MAYBE Greater Good - It's main purpose is to be a sac outlet for your commander. It is also nice against theft decks. Not to mention it can put lands in your grave for you to recur. Lastly, it can make your token created by your commander a fuel for additional draw.

MAYBE Nylea's Intervention - While your commander does allow you to tutor, sometimes it might get exiled, or maybe you want the token more than the land tutor. Not to mention it can destroy fliers which this deck seems to be weak against.

How is the abundance + sylvan library combo been treating you?

Looking forward to your response for each suggestion. I like this deck, I've been thinking of adding Kura to my Azusa list.

Bazzul on Belzenlok, Godo's Ugly Cousin

1 year ago

I’m back after a long break. I guess I’ll answer months after the questions I did not reply to… Sorry to everyone.

igorforkst I am not a fan of Null Brooch the 2-mana price tag is not really viable as we rarely have 2 extra mana to spare when Belzenlok is cast. After Belzenlok ETBs, counterspells are not that much of an issue. We have hand disruption through Grief to remove them and if one goes through, we can still threaten a win next turn.

Nempek I added your suggestions. Specially Grief is the single best card that has been printed in the recent years for this deck. Hand disruption during the turn we combo off is huge. It also has a very effective interaction with Sibsig Muckdraggers giving us and additional cheap discard effect. Regarding your second question, I am almost certain that the deck list you linked has a typo. I believe the player used Dread instead of Dread Presence.

xenca Awesome line, honestly, I like the fact that it uses more efficient combo pieces (artifacts that tap for mana). If you don’t have artifact hate in your meta I would 100% try running this line instead of the regular ooze. Despite the more efficient components of this robot ooze, I still believe Necrotic Ooze should be used by default to avoid being shut down by Stony Silence and Null Rod. The other issue I have with it is that it doesn’t gain Skirge Familiar’s activated ability, thus if an opponent attempts to remove Trazyn the Infinite when Argivian Avenger’s haste ability is on the stack with say Path to Exile and you are out of mana you can’t add {B} by discarding and redo the loop.

Interesting deck, nice low avg cmc. A couple comments, questions and suggestions....

1. Insidious Dreams - Seems like it's prime for a counterspell. I don't see a single way to deal with blue. Moreover, you barely have any draw to even draw into your top cards. I know you have bolas citadel and necro but its not enough. You definitely should consider adding more draw. I know you want to assemble your combo with tutors but more draw definitely can't hurt
2. Sacrifice - How has this been playing for you? I assume you use it in response to an opponent targeting your big demons?
3. Warlock Class - I'm missing something, how is this helpful for your build?
4. Darkness - Does your meta include a lot of creatures/combat? How has it been playing for you, would you consider swapping it out for more draw perhaps?

Suggestions....

1. Imp's Mischief - It can redirect targeted removal, draw, extra turns and can "counter" counterspells. Moreover, it's another useful card to imprint onto Isochron Scepter.
2. Cabal Coffers - Ramp
3. Syphon Mind - Draw and discard. Alternatively, Mind Twist is great to bait blue or ramp into early game to cripple another player.
4. Yawgmoth's Will - Recursion
5. Opposition Agent - Not needed but puts in a lot of work.
6. Mana Vault - Ramp, works well with beseech
7. Phyrexian Arena/Read the Bones/Sign in Blood/Night's Whisper - Decent draw to consider
8. Peer into the Abyss - Super draw that can help you get half your library to find your combos and win. Alternatively, you can target an opponent for politics or you can target them and then cast another spell that makes them lose life = to what they those this turn to finish them
9. Dauthi Voidwalker - As a substitute or redundancy for leyline.

Comments....

1. Are 9 castable instants worth utilizing isochron scepter? I understand the high impact it can have. That being said, you should consider adding additional targets. Isochron itself usually get's 2 for 1ed as well.
2. Your combos don't have a lot of synergy with each other. You have a demon + lifeloss which is a synergy, not so much a combo. You have isochron synergy, not combo, which isn't synergistic with the deck itself. Sanguine + Exquisite is solid, albeit costly. Lastly you have the leyline + helm combo which isn't synergistic with the deck. Rather than having a bunch of combos and tutors in the deck to assemble them as you lose to tempo and blue, why not cut down on 1-2 of the synergies/combos to add more draw or interaction to ensure your deck runs more smoothly and you can more easily protect your main combo and use a backup if necessary?
3. Headgames is solid AF. That card alone is worth upvoting your deck, you have my respect
4. Have you considered going into a bit more a control route? You have contamination that works very help. You have black removal to kill mana dorks but most decks utilize artifact ramp to get around that, what has your experience been with that? Other cards to consider this route are as follows....

A) Infernal Darkness - Its like contamination as it can bait blue, its easier to maintain (usually 1-2 turns is all you need) and doesn't impact your nykthos, lake or ancient tomb.

B) Karn, the Great Creator - It's static ability is a one-sided null rod, in conjunction with contamination/infernal darkness, is a strong soft-lock. It's first ability can help you remove artifacts that you have no other options to remove. It's second ability can bring back bolas, grindstone, painters servant, etc...

C) Null Rod - It does stop about 9 of your cards, but there are other decks that utilize way more artifacts than you.
