Silver-bordered cards are not tournament-legal and are not covered by the comprehensive rules. Usually silver-bordered cards are printed in the so-called Un-sets. Certain promos like the Holiday cards, the 2017 HASCON promos, and Ponies: The Galloping also use a silver border.

Un-sets

Un-sets are named after their common naming pattern:

• Unglued
• Unhinged
• Unstable
• Unsanctioned

Mechanics

They feature mechanics that would be impossible to print in a normal expansion.

Rules
