An iconic tribe dominating both the kitchen table and the commander scene for years, Silvers are embodied by a unique mechanical feel. With each Sliver (for the most part) functioning as a “lord”, Slivers represent the ultimate Tribe when it comes to synergy based decks. With the ability to build huge boards and play cards from every color, Slivers has lacked a true competitive deck, despite moderately successful variants appearing in both Modern and Legacy. With Modern Horizons, that may change, as Slivers are back — this time with mechanics spread throughout Magic’s history. In this deck tech, we’ve broken down the pieces necessary for a new combo kill involving exclusively slivers — and at a reasonable enough rate for Modern playability. While by no means the best deck in the format, Combo Slivers gives players the ability to play both combo and Slivers in a competitively focused package for Modern. We’ll be going over the general approach to the combo, as well as individual card choices for both the main deck and the sideboard.

The Combo

While not a straightforward combo, Slivers now has the ability to create a complete combo kill in the midgame. This combo requires different pieces, and a critical mass of Slivers, but is quite achievable. First, get a Dregscape Sliver and a Basal Sliver into play. This combination means that you can sac any sliver you have in play, and immediately Unearth it. When you have enough slivers, you can sac a Sliver, and return Lavabelly Sliver to the field. This deals one to the opponent and triggers each time you Unearth. Proceed to either get a second Lavabelly Sliver onto the field or enough Slivers among the graveyard and play to kill the opponent. Altar of Dementia serves as an additional combo piece that can combine with Gemhide or Manaweft Sliver to mill almost your entire deck, enabling a kill through either Lavabelly Sliver or by sacrificing large Slivers to Altar of Dementia.

The Slivers

Galerider Sliver | A defining Sliver since its printing in M14, Galerider Sliver is the primary reason for any sort of Sliver playability. As both a one mana creatures for Aether Vial and an evasive threat, Galerider Sliver contributes to many of the aggressive starts. Four copies is a must, to maximize racing.
Gemhide Sliver/Manaweft Sliver | Mana fixing and acceleration is crucial for Slivers, and Gemhide/Manaweft are critical for Turn 3 Collected Company starts. Additionally, these slivers combo alongside the Unearth combo, justifying six copies of this effect. While fragile on the surface, the unique power of these mana generating Slivers contributes to their inclusion. Additional copies can be added in more all in combo versions.

Predatory Sliver/Sinew Sliver | Similarly to Gemhide and Manaweft, Predatory and Sinew Sliver provide a similar redundancy for the aggressive draws. The full four copies of each are likewise crucial, as most games will be won by building a big board. Collected Company for two copies of these ends most games, and they also serve as additional cards milled with Altar of Dementia.
Basal Sliver | Relegated primarily to combo piece, Basal Sliver can build up for a large Rally the Ancestors and Finale of Promise, while enabling the Dregscape Sliver Unearth chains. A couple copies are all that is needed, as Collected Company and Finale can dig for it.

Cloudshredder Sliver | Originally occupying the Blur Sliver spot, Cloudshredder Sliver serves as an additional aggressive compliment to Combo Slivers, while doubling up as a combo piece with Gemhide and Manaweft. A couple of copies are perfect, as it is weaker in multiples and fragile on the surface. Cloudshredder can also be supplemented by Sedge Sliver in more aggressive shells.
Dregscape Sliver | The primary combo enabler, Dregscape Sliver also replaces Diffusion Sliver as the de facto protection Sliver. Combining recursion and aggressive, Dregscape Sliver combines with Basal Sliver and Lavabelly Sliver to create a one turn combo kill. This combo, searchable with Collected Company, gives Silvers a unique pressure on top of the already aggressive components. The lack of battlefield utility relegates Dregscape Sliver to just three copies, though an additional one can be played in versions playing Sliver Legion.
Lavabelly Sliver | Mostly here for the interaction with Dregscape and Basal Sliver, Lava Belly Sliver gives Slivers additional reach alongside a difficult to beat late-game. Multiple Lavabelly Sliver are linearly more powerful, but the weak stats are the reason for only three copies.



Collected Company | One of the defining aspects of creature decks since its printing in Dragons of Tarkir, Collected Company serves as the perfect compliment to both the combo aspect and the aggressive draws of Silvers. Four copies is the perfect number.
Aether vial | Similar to Collected Company, Aether Vial trades the card selection of Collected Company for mana velocity in the mid-game. Enabling busted Turn 3 sequences, as well as enabling instant speed combat tricks, Aether Vial likewise is deserving of four of status. war-160-finale-of-devastation (1)
Finale of Devastation | Making its way slowly into Modern with the introduction of War of the Spark, Finale of Devastation serves as an additional tutor for any of the combo slivers, while serving as a wincon on its own in Basal Sliver or Gemhide Sliver heavy games. In board stalls, Slivers can quickly accumulate the twelve mana necessary to pump the entire board.

Combo Pieces

Rally the Ancestors | Similar to Finale of Devastation, Rally the Ancestors functions as an additional copy of Dregscape Sliver when comboing, and can combine with Basal Sliver and Lavabelly Sliver to push through extra damage. One copy is sufficient in Game 1, and as such an additional copy resides in the sideboard.
Altar of Dementia | A recent Modern Horizons addition, Altar of Dementia combines with Dregscape Sliver to establish a combo kill unlike many seen before. Additionally, Altar of Dementia combines with Rally the Ancestors to both enable Rally and serve as a wincon. While not inherently a great inclusion, a couple of copies of Altar of Dementia enables the combo kill. 


The Sideboard

Chalice of the Void | Never in a better spot than it is now, Chalice of the Void hoses many of the top decks in the format while lacking effectiveness against Slivers. A crucial sideboard card at combating Arclight and Tron, Chalice also serves as disruption against Death’s Shadow and Burn. A fourth copy can be added as necessary.
Damping Sphere | Similarly to Chalice of the Void, Damping Sphere attacks Arclight and Tron but additionally has splash damage against Amulet Titan. The prominence of these decks in the metagame warrants a few copies in the sideboard, but it is far less important than Chalice.
Mindlash Sliver | A flex slot in the sideboard, Mindlash Sliver gives an angle of attack against both Control and Combo decks. Depending on the metagame, additional copies can be added.
Rally the Ancestors | An extra copy of this powerful instant resides in the sideboard, acting as insurance against both removal spells and creature heavy decks.

Dismember | One of the most efficient removal spells in the format, Dismember gives Silvers an effective answer against Thing in the Ice and any of the threats on the Humans side. Additional copies can be added as necessary, though attention should be paid to when to play Warping Wail in this slot.
Harmonic Sliver | A critical piece of interaction in an artifact-heavy metagame, Harmonic Sliver is easy to cast two for one against Hardened Scales but has applications against both Grafdigger’s Cage, Rest in Peace, and Ensnaring Bridge.
Homing Sliver | A flexible sideboard card, Homing Sliver often comes in for slower games, or alongside toolbox sideboard slivers like Mindlash or Necrotic Sliver, by serving as a tutor for these cards.
Necrotic Sliver | Primarily earning its spot due to the mana denial portion, Necrotic Sliver can also fight Thing in the Ice or problematic planeswalkers. At least one copy is necessary.
