Wizards Preconstructed Deck from Legions
They're back! It's been a few years, but Slivers make their long-awaited return in the Legions set, complete with some cool new abilities. The "Sliver Shivers" deck isn't the fastest deck on the planet, but what it lacks in speed it makes up for in strategy and great mid-game strength. Almost all of this deck's creatures can splice their abilities onto all your other creatures in play, and in some cases, even onto cards in your hand!
The key to winning with this deck is patience. Stall your opponent in the early game using your Plated Slivers and Pacifisms so you can survive to the mid-game, when you can drop a Shifting Sliver and outrace your foe to victory. Racing with either Essence Sliver or Brood Sliver is especially attractive, because you'll gain life or extra Slivers each time you attack.
Don't be afraid to hold back on playing Slivers during your main phase if you have
Quick Sliver
in play. You can always wait until your opponent's combat phase if you need a blocker, or until his or her end step if you don't. This deprives your opponent of some information during his or her turn, and can really swing a game if you play a few creatures he or she wasn't expecting.
It can be really tempting to play every Sliver you draw. Sometimes that's the right move, but always be mindful of mass-destruction spells like Wrath of God from the Seventh Edition set. As a general strategy, consider not playing a duplicate of a Sliver that you already have in play. That way you'll be less likely to overextend yourself.
This deck's main weakness is mana. It runs on three colors, and there aren't many ways available to change colors if you're missing one. You might try swapping out some of the basic lands in favor of pain lands, like the Seventh Edition card Brushland, or fetch lands, like the Onslaught card Flooded Strand. Rampant Growth and Birds of Paradise (Seventh Edition) are also options.
Customizing this deck is very easy because there are many other Slivers available to choose from. The Legions set also includes red and black Slivers, and for you nostalgic folks out there, head down to your local store and check out the Tempest and Stronghold sets for the originals. You need diversity to win, and Slivers have diversity to abundance.
