That extra hoop isnt a big problem when presented on cards like Azorius Signet, as you can turn colorless mana into colored mana with the added benefit of skipping summoning sickness
When youre building with flavor, the stuff in the text box (you know, the things the card actually does ) is far less relevant than whats going on in the art and the card name
As a sorcery, you may pay the mana cost of a locked door to unlock it.) If creatures you control deal combat damage to multiple players at the same time, Locker Room's ability will trigger once for each player dealt combat damage this way
Still, in a Commander world of faster ramp, these seem like a lost opportunity
