List of Acorn mechanics

Acorn mechanics, formerly known as silver-bordered mechanics, are mechanics that are exclusive to Acorn cards. So far, these have only been printed in the Un-sets (Unglued, Unhinged, Unstable, and Unfinity). These sets are designed to allow for cards and mechanics that cannot work or be printed under the official rules, and as such, these mechanics have no formal definition beyond that printed on the card. Note that Assemble was first featured as a joke in black bordered Future Sight, but its current rules are strictly Acorn.
