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.
Nether Traitor + Genesis Chamber + Phyrexian Altar can get just crazy with Twilight Drover and Doubling Season. If that isn't enough, Otherworld Journey.
