The owner of this deck hasn't added a sideboard, they probably should...
Start typing a card name and use the auto-complete feature to quickly select the card you're trying to add. Enter a quantity and add that card to your sideboard!
Submit a list of cards below to bulk import them all into your sideboard. Post one card per line using a format like "4x Birds of Paradise" or "1 Blaze", you can even enter just the card name by itself like "Wrath of God" for single cards.
Basic idea is to get Hivestone out so that the Wizards in this deck would benefit from becoming Slivers. With Mana Echoes and Sliver Queen there is the option to create an infinite number of Sliver tokens. With Mycosynth Lattice all mana types would become irrelevant, and all of your permanents would become indestructible from Darksteel Forge.
