Everything in the Sliver Swarm Commander deck: all 100 cards with current prices, what the deck is worth against the sealed price, the 10 new cards, and whether it is worth buying.
The "legend rule" doesn't apply to Slivers you control. Each Sliver creature card in your graveyard has encore {X}, where X is its mana value. Encore {5} ({5}, Exile this card from your graveyard: For each opponent, create a token copy that attacks that opponent this turn if able. They gain haste. Sacrifice them at the beginning of the next end step. Activate only as a sorcery.)
This precon won’t convert long-time sliver-haters, but it provides enough new support for players who already have a coveted sliver deck while also squeezing in a few universally playable typal support cards. It provides fun — but binary — gameplay, and aside from the generic typal tools, it doesn’t offer much for existing non-sliver decks.
However, if you’re invested in playing Slivers, you can follow our Sliver Swarm Upgrade Guide to improve on these unfortunate areas.
The deck title says it all. Magic’s third-ever 5-color precon is a sliver deck, making it one of two typal decks revolving around a creature type with a huge fanbase. Slivers are creatures with abilities that benefit other slivers, making this a tight, synergistic deck all about flooding the board with as many slivers as possible with as many abilities as they can get.
The face commander is Sliver Gravemother, a 5-color Mirror Gallery for slivers that gives them all encore from the graveyard. Rukarumel, Biologist is the back-up commander of the deck, and it turns most creatures you control into the type of your choice. Gravemother is likely the more powerful option if you’re playing straight out of the box, but Rukarumel easily goes on to be the more popular legend in Commander as a whole, since it can serve as the commander for any deck built around a specific creature type.
From a strategic standpoint, slivers have never been the most complicated creatures in Magic, and in a lot of ways a sliver deck ends up playing itself. The play patterns are repetitive but fun, and the creature type has its lovers and haters. Enfranchised players already know which side of the line they stand on, but slivers are always a fun way to invite a newer player into the world of typal decks.
