I decided to remove the sideboard from the cube and it's associating cards. It made games too swingy in the tutor player's favor, often winning them the game on the spot and was leading to logistical issues like lengthy pre-draft instruction and multiple people needing the sideboard cards at the same time. Sadly, this means Spike will have to go but I have decided to replace these by creating some custom cards to enhance and be the missing signpost cards for specific color combination strategies and a few old inquest magazine promos in their spot. A post documenting these new cards will follow and their placeholder spots as well.
