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.
One of my favorite asymmetric strategies is using whatever your opponent has for your own purposes. I have been using Traitorous Blood and Mark of Mutiny combined with Conjurer's Closet to effect this change. The mana curve in a budget deck is fairly steep though. I'm using Arbor Elves. Conjurer's Closet works well with any ETB effects. My focus in this deck is on Acidic Slime since it's been proven to work with Conjurer's Closet. I have not given much thought to a side deck yet, because most MTGO matches where I have played this are single games.
