Get it? Unnerving? And my name is Nova? Un-Nova-ing? You get it.
Just an Un-spiracy cube not unlike any other. Contains 1 copy of each card from all four existing Un-sets (Unglued, Unhinged, Unstable & Unsanctioned), plus Conspiracies for added fun. Conspiracies are allocated at 3 copies of each common, 2 of each uncommon, and 1 of each rare/mythic.

When creating packs, place 1 Conspiracy and 14 other cards into each pack.
Do not shuffle Contraptions into the packs. Instead, compile 1 copy each of all 45 Contraptions and shuffle them into a separate pile. After all players are finished drafting, each player may draw 1 Contraption to add to their card pool for each card they drafted that includes the word "Contraption" in its rules text.
