Arcane Signet has quickly become one of the most played mana rocks in Commander, sitting just behind Sol Ring in inclusion rates on EDHREC. It fixes colours for any multicolour deck at an efficient two mana cost, making it an easy upgrade over weaker rocks. Being printed in many preconstructed decks has helped make it a default ramp option for new players. Ongoing debates about format homogenisation underscore just how ubiquitous this little artifact has become.
