Manaweft Sliver Discussion

TheGodofNight on Moar Slivers

So I took the time to playtest your Sliver deck against mine in 3 games. In Game 1, I went 2-1, The first match, my land base allowed me to get more out before your land base was fully able to come online. The second match, I mulled to 4, but you CoCo'd into a bunch of Lords swinging for lethal. The third match was a repeat of the first one. I was able to get on the board faster.

Game 2, I went 2-0. In match 1, I was able to shut down your Aether Vial with Harmonic Sliver and you just couldn't find enough mana sources to recover from the loss of the vial. Match 2, You were able to bring me to 6 life, but with an EOT CoCo, I revealed two lords, pumping my entire team and 2 Mutavaults into lethal damage range, dropping you 24 points in a single swing.

Game 3, I went 2-1 again. In match 1, you were able to generate a fast board presense than I was and took it. In match 2, with 2 lands, an Aether Vial, and a Manaweft Sliver, I was able to flood the board, while you got to 2 mana and got stuck there. In match 3, we both got online fast, but I hit an EOT CoCo, and then another at the beginning of combat, which flooded the board and let me swing in massively.

Overall, I think your biggest weakness is your land base. I realize that the land base is the one of the biggest cost factors for this deck. I would also recommend that you consider going to 4 on both of the Sliver Lords you are running, and maybe consider the third sliver lord, Sedge Sliver as well, or maybe Metallic Mimic (a slightly more cost efficient route).

I didn't test sideboards, but I'm sure that the results wouldn't have varied too much with them. Overall, I think your deck is definitely an original take on this tribal theme, but I think an update mana base would put it over the top.

Again, I think Sliver Hivelord is a powerhouse, however it is highly susceptible to Path to Exile, which is a huge trade off for your opponent. You waste an Aether Vial to 5 counters (because nothing else mainboard benefits from that) or you spend 5 mana, tapping out, only to have it exiled for a single mana. Mind you, that is not an uncommon scenario, in modern it is more common than you realize, and with Path to Exile recently being reprinted, it is now cheaper and more readily available. In fact, that is one of the only issues I have with the Legendary Slivers, is the cost vs risk factor in a modern setting.

Now, Blood Moon isn't as big a problem for me, I run enough copies of Harmonic Sliver to be able to play through it, and enough Manaweft Slivers and Aether Vials to work around it. Typically though, it is a game killer for most decks running a lot of non-basics. It is worth considering a mainboard Harmonic Sliver. I know you run Aether Vial, but you do not have to play Harmonic Sliver if there is no other target.

Now, for a interesting factoid. Did you know that the most popular board wipes are mostly sorceries? Warping Wails second ability counters sorcery spells, thus shutting down board wipes, saving my slivers. The reason I like Warping Wail is because like the Sliver deck, it is a toolbox card that serves multiple purposes. If need be, it gives me a creature that produces colorless mana, it can remove a small early threat, but most importantly, it shuts down board wipes.

Yeah, boardwipes are the death of sliver decks, but that is also where a 1 of Sliver Hivelord in the mainboard would shine. I will agree with you that the mana base I recommended practically dies to Blood Moon, but that is also where Harmonic Sliver and Manaweft Sliver come in handy. Also, what is the purpose of the 2 Warping Wails in the sideboard? I just feel like there could be better cards to be put in the sideboard in place of those 2 cards.

Normally, I would agree with you, that Blood Moon would scare the hell out of me with a deck with a land base like this, but between Aether Vial, Manaweft Sliver, and Harmonic Sliver; I find I have very little trouble dealing with/or playing through Blood Moon.


The biggest threat to a tribal deck like this is board wipes. A turn 4 or 5 Damnation can be a difficult thing to recover from, and that is were Frenetic Sliver really shines. I probably won't be able to save all of my slivers with coin flips, but since the alternative was losing them all, I think saving some is better than none. As far as Homing Sliver, that is really a silver bullet card, you use it (or another sliver) to fetch up exactly what you need, when you need it. I have been debating cutting the second Homing Sliver in lieu of Rest in Peace or another graveyard hate strategy.

As for the singleton Gemhide Sliver, in response to Blood Moons and cards like Slaughter Games and its ilk, Gemhide Sliver functions as a backup mana source when they remove all of my Manaweft Slivers. Truthfully, it isn't mandatory to keep it, but I have found it far more useful than not.

Both Sliver Hivelord and Sliver Legion are fantastic cards in their own right, but slow as hell in modern (it isn't called the 4 turn format for nothing). They are powerhouses, and if they resolve or go unchecked, you will likely win, but any player worth their salt, won't let them resolve or stick around long.

As for Affinity and Tron (directed more Affinity than Tron), I find that a mainboarded Harmonic Sliver gets the job done and shuts those decks down pretty easily. I have been considering a Blood Moon for the sideboard actually for the Tron matchups as I find that I have a 60-40 win ratio against them, which I feel could definitely be improved upon. I appreciate the suggestions.

I will playtest our decks against each other and see how they perform. I rarely get the opportunity to play against other Sliver decks, so I am intrigued to see how they match up against each other. I'll follow up with results in the comments of your deck.

This is a good start to the deck. Knowing your collection, I am sure that you must not have many cards.

But I like the way you use Blades of Velis Vel in order to get that sliver synergy. That's a sign of a good player being able to see these unusual interactions. So if I were you, the first thing I would do is to get more slivers.

A good low curve Sliver that gives good buffs would be Predatory Sliver. He's also cheap so that's a plus. Muscle Sliver is the same thing but a little more expensive at a dollar a piece. But having 8 of these guys is pretty good. Blur Sliver is also another really great cheap option as it gives all of your Slivers haste, a great way to close out games quickly. Manaweft Sliver is also an important card as it allows you to ramp up to your Megantic Sliver which is what I am assuming you are trying to do. Gemhide Sliver can also fill the same role. Hibernation Sliver is also a fairly cheap option that can save your Slivers for the low low price of 2 life. Sidewinder Sliver is also really cool, and can make your slivers even harder to block.

What's great is that most of these cards are under a dollar, making a budget deck with these guys extremely viable. The only problem is, the mana base could be more expensive. Having all of these Slivers is great, but if they are stuck in your hand because you need green mana when you have white, that kind of sucks. So in the interest of budget lets make a budget mana base.

First Darksteel Ingot is pretty great. I'd run 4 of them. Transguild Promenade and Evolving Wilds are very cheap options that can get you any color. Lay of the Land can also fix pretty well. Rampant Growth can get it on the battlefield. These are all budget options however. The best option would actually be Birds of Paradise, but at $5 a card, it can be kind of expensive for a new player. What's great about them however is the synergy with Blades of Velis Vel. Play that on your birds and you suddenly have a huge sliver bird swinging in the air. If you have the money definetley get a playset of these birdies. Another option for mana fixing can also be found in the Ravnica Guildgates. All very cheap options to fix your mana. Sliver Hive is more expensive, but works great in a slivers deck.

If you were to build a Slivers deck I would highly recommend upgrading your mana base first. That inclusion will be able to help you do whatever you need to do with your actual creatures. Assuming a budget of $20 this is what I would recommend.


Predatory Sliver x4

Muscle Sliver x4

Sinew Sliver x4

Striking Sliver x4

Two-Headed Sliver x4

Suntail Hawk x4

Wild Nacatl x4 (you could also go Kird Ape if you want to be cheaper).


Blades of Velis Vel x4

Shields of Velis Vel x4

Mana Base

9 Forests

8 Mountains

7 Plains


Spinneret Sliver x4

Tormod's Crypt x2

Smash to Smithereens x2

Shock x4 (preferably Lightning Bolt, or Path to Exile but those cards are expensive).

Elite Vanguard x3

I'll make a tappedout list of this later, but this should hopefully be under $20. At the very least it is $25 for a very powerful aggro deck that synergizes really well. I took out the bigger cards such as Megantic Sliver in favor of cheaper slivers that are easier to play. The Velis Veil cards are great, and can surprise many opponents. The sideboard includes Spinneret Sliver to deal with flyers, Tormod's Crypt for graveyards (can also deal with Gift of Immortality wink, wink, nudge, nudge). Smash to Smithereens for artifacts, Shock for cheap removal, and Elite Vanguard in case they do run a lot of flyers. Upgrades to the mana base should also be considered.

Wow that was a long post.

Sinew Sliver and Manaweft Sliver could be nice additions.

Thank you DaringApprentice and UnleashedHavok for the up-votes! Just threw the deck together on a pseudo-whim. Any time my friends mention they want to make a deck and then don't for several months I do my own take on the commander and/or theme. My friend has a Sliver deck on a legal pad and now I'm curious how they stack up.

I've been playtesting on the site here (ten-turn samples--no opponent) and the mana base works better than I thought it would. The ability to tutor up Harmonic Sliver, Dormant Sliver, Sliver Hivelord, Gemhide Sliver/Manaweft Sliver, or Necrotic Sliver is sooooo damn cool.

Sliver Overlord is a much better commander. I don't know if its out of your budget but it can fetch all the slivers you need. Training Grounds is also a very good card to go along with it. If you've got the money Sliver Legion is another good investment. Paradox Engine can also help after you have manaweft and/or gemhide out. Coat of Arms because its a tribal deck. Chromatic Lantern so you can get all colors easily. Mana Echoes because its tribal and because it basically lets you go infinite. Sliver Overlord+Paradox Engine+Manaweft Sliver/Gemhide Sliver+Mana Echoes= infinite mana as long as you can search and play more slivers.
