Very strong in Commander. Often better than mana confluence considering the ubiquity of mana rocks and the fact that it can produce colorless, let alone that you can use it without taking damage when you don't need the color.
I've seen many a glimmervoid cut from a frustrated affinity player's list, since a) its always 1 Hurkyls Recall away from the GY and b) there are opening hands with only a glimmervoid that can be really awkward.
I think the life cost for the rare case you need colored mana is probably worth the tradeoff vs the risk of glimmervoid. I suspect it will just replace that card completely in modern affinity lists.
This land sucks unless you're running 5 colour good stuff which is a full proof deck of every colour and why is this land yellow if it only produce colourless mana and even though it produces and mana type it should be some sort of artifactland as its like a scyscraper
