I think I may have deciphered the "green door" card from The Hobbit set
What if it's Arcane Signet written in runic script?
Cost: 2 colorless
Type: Artifact
Title: The glyph pattern matches exactly with "ARCANE SIGNET"
Rules text: 11 words — which matches perfectly with
"Tap: Add one mana of any color in your commander's color identity."
Glyph structure: Consistent with the sounds and layout of both the title and the rules text
What do you think ?
