MTGeni.us Uncube
Uncube colloquially refers to a Magic: the Gathering cube dedicated to cards that are only legal in the Cube Draft format, primarily focused on silver-bordered cards.
This uncube, in addition to silver-bordered cards, contains unreleased Magic: the Gathering artwork, cards from unreleased and digital-only sets, emblems for those cards, and tokens for those cards.
In order to support Super Secret Tech, creature cards and cards with generic mana costs are premium if they exist as paper prints.
