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.
Very much in progress, just a thought.
In progress - The idea is to use Quicksilver Fountain to actually make enemy lands islands (cutting their mana supply and giving your creatures an island to walk on), using creature abilities like Streambed Aquitects to give Islandwalk or that defending island, and then blue ramp with high tide and Silver Myr to get out my Leviathans and Whelming Wave to give them superiority over all other creatures.
