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.
The idea is cast spells that have a cheap flashback cost, repeatedly feeding them to Nivmagus Elemental then use Artful Dodge + Mizzium Skin to swing in for the win.
