Caves of Koilos Discussion

Gadianten on Divine Machinations

Out: Cabal Ritual, Dark Ritual, Doomed Necromancer, Ancestor's Prophet, Mentor of the Meek, Caged Sun and Boseiju, Who Shelters All

In: Ravos, Soultender, Academy Rector, Phyrexian Arena, Edgewalker, Tymna the Weaver, Caves of Koilos, and True Conviction,

I am experimenting in reducing mana costs in creatures abilitie as the deck tends to be mana hungry. Also, I have tried to shift closer to having it as cleric heavy as possible. True Conviction was put in as a secondary target for Academy Rector and general bad news for opponents. I will also be looking to reduce the amount of colorless in the decks lands to help speed it up.

casmiel on Budget Orzhov Control Deck

Ultimate Price is always worse than Go for the Throat (both can't hit artifacts)

I'd play Condemn, Path to Exile, Fatal Push and even Anguished Unmaking over Utter End.

Despise is not really a strong discard spell, I'd rather have Duress, as that usually hits the most dangerous cards. Of course Inquisition of Kozilek and Thoughtseize are better than both. If you want to stay budget, which I assume, why not go for Tidehollow Sculler or Sin Collector? Both are really strong cards, even in competitive Modern.

i'd bring your landcount to 23. Try to get the full playset of Isolated Chapel. Concealed Courtyard and Caves of Koilos are affordable as well. Evolving Wilds is not great and would just be an emergency solution. Either way, you need more dual lands to have reliable mana.

Vampire Nighthawk has some strong competition in Gifted Aetherborn now. But you need more dual lands, otherwise it is too difficult to cast reliably on turn 2 or even 3.

I've seen some decks that run Tainted Remedy as the cornerstone to play cards that grant the opponent life. You don't have enough lifegain cards to make that a viable direction though, it's also much more vulnerable and combo-like.

I see what you are trying to do with Niblis of the Urn, but it is a pretty weak card overall. You should find another alternative for tap-effects, that one is a bit weak. Or just go with more removal, no tapping needed then. Luckily, Black and White have the best removal.

The appeal of Black & White decks comes from Lingering Souls in most cases, which is a pretty insane card. It will drive any Control player mad, as it is a nightmare to destroy with removal. I would highly recommend slamming it in any B/W deck, you almost can't go wrong there. It works well with Cartel Aristocrat, but that would go in a completly different direction I suppose.

Edge of the Divinity is a good, but problematic card. It makes your opponent's removal twice as good, but it offers a cheap and strong boost. I'd say only ever run Auras in Modern if you put it on a Hexproof creature. Even if you'd ignore that for now, this card wants to be played in a highly aggressive deck. Your deck is a bit too slow for that to work out, so I personally wouldn't run it.

Underworld Connections is much worse than Phyrexian Arena. Asylum Visitor can be an alternative if you really need the drawing power. It is cheap and can usually trade with something else.

Ambition's Cost is pretty much unplayable in Modern. Night's Whisper, Sign in Blood and the cards mentioned above are much better when it comes to drawing cards.

I wouldn't focus your deck towards Alms Beast too much. Just use it as a finisher and your top-end card. You should decide which direction your deck should go. Either you go down on creatures, and instead increase removal and hand disruption, maybe add some Mana Tithe and play Orzhov Control with the Beast as your finisher. Or load up on creatures, cut your draw and removal and go aggressive, with creatures low in cost and high in power to go wider. Either way, both varieties would be stronger than what you have now, which is sort of a mix of both and that never really worked out as far as I know.

Good luck with the deck!

Hey man, i'm looking for the MM15 version of Remand for the artwork.. For the Caves of Koilos, i'm looking for the Magic Origins set for my matching playset. So i'll pass on Remand and Cave if it isn't origins.

Definitely interested in Dovin Baan, Tamiyo, Field Researcher, Sorin, Grim Nemesis, Sol Ring, Elspeth, Sun's Champion, and the Foil MM Path.

I was away from the site for a while, but I saw you wanted a Sheoldred too.. I have the promo version if you still need her, or want that version. I'm using the regular version for a deck.

i'm not a price whore, we can use the prices laid out here if you want? Let me know what you're interested in from me for those cards you have.

Spootyone on Mummy? Are Zombies Real?

Alright sounds good. I'll keep my advice to that then.

First things first, let's deal with the basics. The land count of this deck is a couple short of where it should be at given your curve. As you may already know, most decks sit comfortably at around 24 lands, and I think the curve on this deck is going to end up in a spot where 24 is the correct number. The lands, themselves, also could use some retuning, as you seem to be using some very suboptimal choices when there are better ones out there. For example, you are running arcane sanctum, which is effectively a "bad" Orzhov Guildgate in this deck. You could instead be running 4 copies of Concealed Courtyard, which would be a great alternative. If that is not in your budget, then even Scoured Barrens or Temple of Silence are marginally better alternatives.

Additionally, I think Sunscorched Desert doesn't have a real place in the deck. The colorless mana is going to be a severe hindrance to you and dealing one damage isn't going to matter nearly enough. Cradle of the Accursed is also a little mediocre at the cost of not tapping for any colored mana, so I also think it isn't good enough to make the cut. Budget withstanding, I think this is how I'd run the mana if it were up to me, but with still keeping the general base you had:

4x Concealed Courtyard

4x Caves of Koilos

4x Isolated Chapel

3x Tainted Field

1x Urborg, Tomb of Yawgmoth

6x Swamp

2x Plains

The main thing to note about this mana base is that it is Swamp-centric. Many of the dual lands require you to have a swamps on the field before they become real duals. Godless Shrine would be great because of this, but its also a little pricy. Let me know what you think of this before we get to anything else.

Iron_Cube on Doran, the Tree King

I'm playing most of your cards in my decklist. But you're missing Murmuring Bosk. I would probably add Hissing Quagmire and Shambling Vent instead of Vivid Meadow, Terramorphic Expanse or Evolving Wilds. Fetchlands (Verdant Catacombs) would be best, but you can still use these for budget replacements. I would strongly recommend to add the shocklands (like Temple Garden), or at least some painlands (Caves of Koilos, etc.). Because you can use them the turn you play it.

As for the rest of the deck it's up to you. It looks good. Personally I prefer Dark Petition over Diabolic Tutor if you can get the mastery...

EmmetCooper Organising a deck by rarity is not a helpful way to look at it, the default of card type is much easier to read...

Moving on, Caves of Koilos or Isolated Chapel as they don't enter tapped and can produce both types of mana, meaning your not stalled for a turn. Gifted Aetherborn should replace Child of Night as it is functionally better. Your deck looks to be top heavy, by this I mean you have 15 spells at 4 cmc or greater. Generally you want most of the work to be done with 1, 2 and 3 cost cards then you have some "finisher" which close the game. Generally you also want consistency, that means you focus the deck more by running 4x of the core cards.

General cards to look at -

Creatures: Athreos, God of Passage, High Priest of Penance, Tidehollow Sculler, Souls of the Faultless.

Spells: Zealous Persecution, Duress, Brave the Elements.

Planeswalker: Sorin, Lord of Innistrad or Sorin, Solemn Visitor

This isn't an exhaustive list, there are lots of other cards that cause your opponent to lose life and you to gain, or play to that tactic.

Hope that helps.

@Argeaux: Ah so it was just Mind Over Matter/Skullclamp all over again lol.

Do you know if there were any issues at all though with the changes to the schedule? Normally, they design blocks 2 years before they rotate in. With the changes to the Standard format release dates, were there any issues for R&D that caused them to overlook things because of time?

@Homura_Akemi: Part of the problem is experienced, long-time players don't buy sealed product. We buy singles on the secondary market. The only time we ever buy sealed product is for Limited. IMO, this is entirely WotC's fault. I don't feel like spending $4 for $1 worth of cards. However, I jump all over the chance to buy things like Commander pre-constructed decks, From the Vault, etc. WotC really doesn't make enough of these products, and they don't always make them to match their value. Even some of the Commander decks are only worth $20 when their MSRP is $30.

Obviously, they can't just make decks filled with a bunch of overpowered nonsense or come with 4 copies of Jace, the Mind Sculptor and 4 Tarmogoyf. They could, however, make decks that are actually playable for an FNM. For instance, budget Infect or RDW sold in precons that have 4 copies of their important cards with rares that actually fit the deck, along with the correct types of lands.

The event decks are a step in the right direction, but they're also rather lacking. The B/W Modern Tokens deck was okay. But seriously? Only 3 Path to Exile when the deck needs 4? 2 Inquisition of Kozilek with no Thoughtseize? Elspeth, Knight-Errant as the mythic? A mana base consisting of 4 Caves of Koilos and 2 City of Brass? The value was there, except it wasn't in the right places.
