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.
This deck is designed on an exchange theory. The goal is to take control/possession/or ownership of everything your opponent has. It is a multiplayer control deck. Save the Whispersilk cloaks for the Beguiler of Wills or perhaps a Master Thief that has taken possession of something incredible like a Platinum Angel. The Take Possession is used primarily for counteracting Planeswalkers by stealing them. I was able to purchase Beguiler of Wills for under $1.
