Gruul? Moar liek drool!

Strictly worse than Azorius Signet

Strictly worse than the Moxen; those only make one colour.

Seems like you could find alot of Gruul signets smeared on the wall of gas station bathrooms

Not seeing any blood, snot or muck on that thing. What am I supposed to think from that?

@Kirbster, you think that wall is made of bricks and mortar?

The signets were replaced by the cluestone cycle when we returned to Ravnica probably due to how powerful the ability to produce colored mana of multiple colors at once can be, especially in limited. Being colorless, signets help fix your mana even if you aren't running the colors of the guild - this can be handy if you're splashing a powerful spell in a deck composed of other colors. Furthermore, it's also just additional mana if you're using it for that. Imagine a card like this:

Name: Blank Signet
Casting Cost:
Artifact
, : Add to your mana pool.

Not incredible, but completely usable in limited.
