Cavern of Souls Discussion

stylejoker00 on Modern CoCo Slivers

Scorprix Sentinel Sliver is in there because of my meta. I find that having blockers up is a necessity in a meta full of other tribal decks, and in my own experience, it's been a really nice card as a two of. Since I've received so much critique about it, however, I have decided to change it out for some different Slivers.

As for Phantasmal Image I dislike it for two main reasons:

1) If it gets targeted by anything from my opponent, it gets blown up. That's incredibly easy for my opponent to do. As someone who mains Ponza as a modern deck, I have literally killed Images by buffing them with Kessig Wolf Run . It's one of the reasons I really dislike playing it in most of my tribal decks barring Spirits.

2) Cavern of Souls , Unclaimed Territory , and Sliver Hive do not produce colored mana for Image, unless I specifically name Illusion for two of them, which shuts off those two lands' ability to make mana for the majority of my creatures. Furthermore, this is a CoCo deck with Slivers and Sedge Sliver , arguably the best or one of the best three drop Slivers in Magic. That means I need lands that produce green mana and swamps to reliably cast and benefit from two of the best cards in my deck. Since Image does not synergize well with Cavern of Souls and Unclaimed Territory (it would be a different story if Image had changeling as an ability), that means I would have to add more blue-producing lands which is difficult in a deck that runs 5C Slivers and requires the aforementioned green and black sources for CoCo and Sedge.

Hope my reasoning helps clear up some of your questions!

VexenX, I have also used Sylvan Scrying to get Yavimaya Hollow , Cavern of Souls and Command Beacon . Am I the only one who has waited a turn to cast Omnath because I wanted the extra green mana to activate Yavimaya Hollow?

I would be interested to see how many activations Wrenn and Six gets in decks using our creature base if cast before Omnath. Remember we start with a maximum of 12 creatures. Purphoros, God of the Forge is not going to have enough devotion most games to be a creature on the battlefield. Craterhoof Behemoth is a finisher and won't be there to block. Avenger of Zendikar is probably another late game cast.

What besides Sakura-Tribe Elder and Eternal Witness would you consistently be ok with blocking and losing to protect Wrenn and Six? Maybe with no lands in hand you are ok with losing the extra land drop creatures with the exception of Oracle of Mul Daya .

You stated that you expect to utilize Wrenn and Six "for a couple of turns (at least)". I think this is very optimistic especially considering you are talking about turns 2-5. Maybe I am wrong. I will chart the times I have Sylvan Scrying in hand and wish it was Wrenn and Six. But remember, we have to consider board state and factor in the number of probable activations.

Scorprix: getting to 4 mana is usually not hard with 24 lands. i've been using 5c slivers in modern for over 3 years now, and my only rainbow land is Sliver Hive (can't afford Cavern of Souls yet). the rest is fetches, shocks, and basics. i almost never have problems getting the colors i need.

Hey there Demonio_de_Laplace thanks for the comment!

  • 1: Cavern of Souls ; Good point! at the moment most Mono blue list except for Arcum don't play caverns at all. within a meta where blue is more dominant, this indeed is a very good slot!

  • 2: Stasis is a gameplan you can't really work around with Urza because unlike Teferi, for example, he can Untap artifacts and make it somewhat asymmetrical consistently and abuse it way more than Urza could. if you feel like you need to stall more and want a Stax heavy build you could go for it as it's still better than Trinisphere for this deck and you could prolong its lifetime if you keep drawing into castable artifacts.

  • 3: Candelabra of Tawnos is undeniably a good utility card in storm/tide decks. It is Not essential, but it smooths your storms turns out a lot and makes High Tide lines really really effective. Of course, this is not a number one priority card for the deck and shouldn't be considered first if you're going to spend money, You should be better of getting fetches, duals, ramp artifacts and all that first before i would recommend someone to get one as you'll really commit to the deck by then...

GeminiSpartanX, you and I are like minded on the land tutors. I never cut Crop Rotation and Sylvan Scrying and have NO plans to do so in the future. They are good at every stage in the game.

Wrenn and Six seems like an inferior choice to either of the above listed cards. I will compare it to Sylvan Scrying as Crop Rotation is the vastly superior card to Wrenn and Six and the debate would be pointless.

Wrenn and Six, with our low creature count, is most likely getting one activation if cast before Omnath and the arrival of the elementals. Sylvan Scrying always gets ANY land. Sure IF Wrenn and Six survives mutiple turns and there are land cards in your graveyard it is the superior card.

But, unlike Sylvan Scrying it is not good in every stage of the game. It can't help the deck overcome difficult metas such as heavy control and heavy removal. Sylvan Scrying does just that by getting Cavern of Souls , Yavimaya Hollow and Command Beacon . All of this is just icing on the cake for Sylvan Scrying as it gets one of the best cards in the deck in Gaea's Cradle . One could argue that Sylvan Scrying has a higher floor and ceiling than Wrenn and Six.

Seems like a pretty decent Avacyn build! With as many angels you have in your deck, Cavern of Souls is a no brainier. It's the single most important card in my mana-base for my Avacyn build. I've dedicated the last 6 months or so to working on this build.

Check out my Avacyn build here:

Guerte: I think all your changes are great. I am just struggling to figure out if I can make room for Circuitous Route in my deck yet. I don’t want to cut something with CMC smaller then , but everything the same of above seems too good to cut. What do you think about cutting one of the token doublers or Splendid Reclamation ?

Sylvanrush: I don’t see a problem with running the Nissa package, I am just not a big fan of Planeswalkers in Commander for the most part. The exception I make with Wrenn and Six is because of its CMC as well as the fact that I really don’t mind if it dies after one use. Two mana for a land from the grave is not all that bad, and if it lives then it is pretty fantastic after that. The problem I have with all the Nissas is that if they don’t survive a couple turns then they are really bad! I think mainly about playing them on curve. So although Nissa, Who Shakes the World could ramp you a ton if played with a couple lands open, if you play here and only get 2 mana (after untapping one land with her+) then that is a pretty bad turn. Regardless, still not bad cards overall, just not my thing. I would definitely play Evolution Sage if you go more of a Planeswalker route though!

When it comes to Boundless Realms I always felt like it was a bad play about 80% of the time when I had it in hand. I have played then deck easily over 100 times and have always felt this way. It has been in the deck so long only because of these handful of times it did really cool things. I think there are better options out there though, like earlier ramp spells for have the CMC.

As you stated, I removed a couple “search for any land” cards from the deck, but also added Crop Rotation . When I search it is almost always for Gaea's Cradle and maybe sometimes Command Beacon (if against heavy black) or Cavern of Souls (if against heavy blue). Going down one search ability overall won’t break the deck I think, but only playtesting will tell us.

The odds of Wheel of Fortune giving them Cyclonic Rift comes up as often as if it would make them discard it. The risk is worth the reword when it comes to refilling your hand though.

Ruggs: Thanks for the support man! I think the deck is a ton of fun too! The Finale of Devastation debacle was discussed a bit above. Although you just win if you cast it for 12 mana and Avanger is not in your hand, that is a ton of mana for something that can be done by other cards, such as Tooth and Nail for Avenger of Zendikar and Craterhoof Behemoth . The only way it gets in the deck is if I take out Natural Order or Chord of Calling . Do you think either of those are worse? I am not against adding it, but I don’t think I need three tutors.

Eledain and stylejoker00: its also important to note that the "unearth" ability does not target, and so would not be impeded by "shroud", even if the shroud extended to slivers in the graveyard.

i've been running slivers in modern for a few years now, and noticed a few places in your deck where improvements could be made.

  1. run 24 lands. an easy way to make space for more is cut the Birds of Paradise and Mirror Entity . you won't need them. land drops are more important than a mana dork that is only good early game, and slivers won't need any p/t buffs from the mirror entity. they have plenty. 24 lands ensures you can still usually cast Collected Company without a mana-sliver, and gives more opportunities for color fixing.

  2. cut any sliver outside of Collected Company range. Sliver Hivelord and The First Sliver are good cards, but they don't function well in an aggro vial/coco build. slivers put into play with vial or coco won't trigger cascade.

  3. you need more swamps for Sedge Sliver . yes i see the Urborg, Tomb of Yawgmoth , but you still only have 7 total cards that count as a swamp or go fetch for a swamp.

  4. increase the number of lands that can tap for green for Collected Company . currently, you have 8 lands that can produce green or search for a green source. my recommendation would be to axe the Sliver Hive . yes its a rainbow land, but with proper distribution of fetchlands and shocklands, the Cavern of Souls alone should suffice for rainbow lands.

  5. Phantasmal Image . this guy is great for copying any stackable sliver effect, most notably the power boosts. but it can also come into play copying Harmonic Sliver , and then you get to blow up 2 artifacts/enchantments.
