Doesn’t need them? I’m running Harmonic Sliver as targeted enchantment/ artifact removal and it can be bounced with chulane to be used again.

Dropped Crypt Sliver for Harmonic Sliver. Realized that crypt didn't synergize with Crystalline Sliver.

Starting from the Premium Deck is a pretty good place to begin crafting slivers and it's what I did myself and have been playing slivers for a number of years now.

Now for quite a lot of suggestions and thoughts that I hope will be helpful for you

Recommended Cuts

You really don't need Mana Reflection in slivers or most other decks for that matter. It's really a "win more" kind of card and if you're doing well enough that you have the 6 mana to burn on it you're probably better off just dumping more slivers into play or tutoring for slivers that will allow you to win the game with your Sliver Overlord. If you're using it to go infinite and win with Sliver Queen then your Mana Echoes will provide the same effect for that combo but either of the 4-cost token doublers can also work. Anointed Procession Parallel Lives

You also don't really need bombs like Ulamog, the Infinite Gyre, when you can spend less mana on more creatures that generate more value, putting 11 mana into a single creature will feel kind of bad. Also, a 10/10 among a board of 20/20 unblockable, vigilant, double striking, lifelink, flying, deathtouch, trample, etc. creatures isn't going to provide much of a bonus, it actually ends up being less of a threat than the rest of your board. Plus, if it gets countered, you’re down 11 mana whereas if somebody counters a sliver then you’re down like 2-4 mana and can still play more slivers.

Mycosynth Lattice opens up your entire board to artifact removal (including your lands) you may want to reconsider this include as it doesn't really provide any benefit to you for all the risk that comes with it.

Sensei's Divining Top may not be as useful in a deck where you have as many tutors as you do and your commander can tutor all your value pieces since you’ll probably be shuffling your deck a lot.

Amulet of Vigor doesn’t actually do that much for you, out of all your permanents there is only one that always enters tapped, Vesuva. With the number of shock and check lands you run, you probably do not need this and can use this slot for something else. (I get that it also works with Cryptic Gateway but without a source for card draw, you’ll run out of slivers to play quite quickly anyway)

Quick Thoughts

Crystalline Sliver turns off any and all "target sliver" abilities like Crypt Sliver and Magma Sliver (You also won’t be able to steal things with Overlord). If you find yourself subject to frequent spot removal and need to bring Crystalline out often to protect your Slivers you can at least keep the regenerate ability with Clot Sliver or Sedge Sliver

Harmonic Sliver can potentially ruin your infinite Token Queen combo as the pieces that enable that combo are all artifacts/enchantments and this sliver’s ETB is not a ‘may’ ability. You must destroy something if there is a legal target on the board so you would end up destroying your Training Grounds, Mana Echoes, etc. If you still want this ability I would recommend swapping this with Aura Shards as it is the same ability with the same trigger but it is a ‘may’ ability and you can choose not to destroy something.

Useful Slivers

Hibernation Sliver is one of the best slivers for avoiding removal. Paying 2 life to protect any sliver from being destroyed, exiled, stolen, etc. is very useful

Belligerent Sliver/Two-Headed Sliver making it harder to block your slivers means more bodies getting through to hit face.

Essence Sliver this is not Lifelink, and because it isn’t it actually stacks with Syphon Sliver for more life points

Dormant Sliver It’s fairly easy to dump your hand when playing slivers but this leaves you with an empty hand and not a whole lot of options. Very good for keeping your hand full of slivers to play. Defender can be a problem but who says you have to attack to win with slivers ;)

Screeching Sliver alternate win, tack this onto infinite sliver tokens combo from the Queen to mill out your opponents. Good if locked out of attacking for some reason

Lavabelly Sliver another non-combat win with Queen combo

Homing Sliver another way to tutor for any sliver you need besides Overlord’s ability

Mesmeric Sliver only card with Fateseal in the game, great for controlling your opponent’s next draw. Force them to only draw lands or maybe give them no lands at all.

Necrotic Sliver having spot removal for any permanent on every single one of your creatures is terrifying a very valuable. Strongly recommend this as an include.

Shadow Sliver I have never encountered anyone playing creatures with Shadow in EDH in all my years of play. This most certainly will let you get through and hit face to win a game, just make sure you kill all your opponents or get rid of it after combat as it leaves you with no blockers

Virulent Sliver I know there are mixed feelings about poison counters in the magic community but hey you get 2 counters on someone with double strike creatures.

Fun and Useful Tribal Cards for Slivers

None of these are particularly pertinent includes and some came with the Premium Deck, but these are just some Tribal cards that I have used over time while playing with slivers. Some I still use and some I do not.

Kindred Summons, Wild Pair, Herald's Horn, Coat of Arms, Kindred Discovery, Descendants' Path, Patriarch's Bidding, Kindred Charge, Vanquisher's Banner, Distant Melody, Kindred Dominance, Living Death, Primal Surge, Harsh Mercy, Door of Destinies

Closing Thoughts

Slivers can be a lot of fun to play but keep in mind that they are very aggressive and can draw a lot of hate from your opponents. Players that have experienced playing against slivers are likely to counter your high-value creatures like Gemhide or Queen and will try keeping your board as small as possible since slivers win by swarming and overwhelming your opponents. I have found that this can be mitigated somewhat by changing your commander since slivers have 3 good options. Sliver Overlord, Sliver Queen, and The First Sliver.

Overlord and Queen are quite similar as they both conducive to trying to hit Queen’s infinite combo as quickly as possible but I have found that Queen tends to make people more nervous than Overlord does since you can create a wide board very quickly with her. Not only that but if you are relatively uninterrupted then silvers can combo out relatively consistently by turn 4 or 5 (depending on how lucky you get). If you like a combo victory, then that’s great, but the combo has very little variance and I personally got bored of it after playing it like that for so long.

Using The First Sliver as your commander is a whole lot less consistent if you’re going for combo but overall I’ve found it to be significantly more fun to play as I can sometimes rip 3-4 slivers for free off the top of my deck. The win is the same with overrunning your opponents but not using an infinite combo every time was very refreshing.

Hopefully you find some of this helpful, slivers are my all-time favorite tribe in mtg and it was great to see them get some love in Modern Horizons.

Frenetic Sliver is cool, but unfortunately is inconsistent. That alone bars it from being considered a viable competitive option. But is it cool? Heck yeah. It does have some awesome synergy with slivers that have ETB effects like Harmonic Sliver . Dregscape Sliver leaves me a bit apprehensive - because in my opinion I think it's only good for one really big play after your graveyard is filled up with a bunch of hivelings. If you can't kill the table on that turn, then best case scenario you'll bring back specific slivers and get an infinite combo to seal the win. Worst, and probably most likely scenario(s): someone will use some graveyard hate (at least in my meta) or someone will remove one key Sliver ( Gemhide , Queen , or Basal ) preventing an infinite combo from going off. So instead you make some big play and deal a bunch of combat damage - killing off some of the table but not all. Then all or some of those resources are exiled and you're in a relatively decent position.

Having to rely on Frenetic 's ability to avoid the Exile effect of Dregscape is just too unpredictable for any competitive Sliver deck. But, it's very fun in a more casual deck, and i'd honestly recommend it - seems like it'd be a blast to flip coins and have the table be like "Is it going to get exiled?!".

lil_cheez Thank you for the suggestion! I hadn't even considered that Aura Shards isn't Modern legal. Harmonic Sliver is indeed a legal, way more budget friendly suggestion. I'm putting it in immediately. Thanks! And yeah my version started off as a budget deck, but I had such a blast playing this deck I kept upgrading it with the lands and the Fauna Shaman . If you cut those it's an incredibly budget friendly deck!

Love the concept! I'd totally play this, but my version would be even more budget for casual play.

Aura shards is not modern-legal so if you want to keep that hub maybe Harmonic Sliver will do.

Another thing I would maybe suggest, is that because your mana reliance is a little heavier on green, you probably want to reflect that a little more in your mana base. Also, unless your meta doesn't play tribal decks, be wary of Coat of Arms as this can benefit your opponents. Maybe a Door of Destinies could be more of a safe creature buff?

Also, a word of warning, be wary of Harmonic Sliver , this is a must trigger, and if you don't have Darksteel Ingot out and there is no other valid targets, you may be blowing your own stuff up. Having an Aura Shards may be a good addition because of that movely word... May. I'm sure you have already thought of this, but I learnt this one the hard way lol.

To start with, your deck is false. Secondly I would remove Brood Sliver for Magus of the Moon to help with your prison strategy, Remove Crystalline Sliver for Blood Moon , Harmonic Sliver for Back to Basics , and lastly remove The First Sliver for Hazoret the Fervent . I would also look to add more sweepers, counterspells and lands.
