For whatever reason, I find the title funny, because it only makes sense to MtG players.
Anyway, the other day I made a couple of two-colored lists around the devoid mechanic. Later I realized I completely forgot about this card:
… which kind of makes things easier.
First: This is speculation. Not many cards are out, so I can’t really say how many sources for colorless mana you’ll have, but I’m basing this on the idea that we only have the [scryfall]Wastes[/scryfall] as a source.
This is strictly a thought experiment. I was looking at Todd Anderson’s and Brian Braun-Duin’s video on SCG yesterday. Anderson was playing a version of Esper Dragons (and winning), while BBD was playing a monogreen deck. That latter deck had plenty of “spell lands”, such as [scryfall]Foundry of the Consuls[/scryfall], [scryfall]Sanctum of Ugin[/scryfall] and [scryfall]Spawning Bed[/scryfall]. It had total of ten such lands.
I thought to myself, “well, the mana is very good in the format, but the format also has plenty of good colorless lands, maybe we could do a colorless deck?”. Can we? Probably not, because colorless creatures are always much higher on the curve than similar creatures with colors (with the expection of [scryfall]Wurmcoil Engine[/scryfall]). It will be a slow deck, but I wouldn’t completely discount it. Just mostly.
