This looks like my jam. I read your blog post about having a hard time finding an archetype for UW and UG.

Turns out in Core2019 UW has an artifacts draft theme, also worth noting, Dominaria’s “historic” draft archetype was also UW. Maybe there’s something to that, since all artifacts are historic spells.

Have you considered counters to be a UG thing? Between energy, charge counters, proliferate, and fabricate there might be a definite deck here. Maulfist Revolutionary and Skyship Plunderer would be really cool here.

Thanks for the input MrLizard! I haven't updated this Cube since Ixalan so I definitely think there will be new cards from Dominaria as well as from M19 but I might have missed the archtypes you mentioned.

UG was counter heavy in some point of my draft but to me it seemed that it was the easiest way to go and I wanted to try something else. It's also worth noting that counters are so abundant these days that they might make the combination too strong. Maybe.

I hope you don’t mind, I’d like to make this the base of my next cube project. A skeleton if you’re cool with it.

Also worth noting in a cube like this Baloth Cage Trap is always a 4/4 for 2 with flash, which may be on the stupid powerful side and Trygon Predator is probably straight unbeatable.

MrLizard by all means! I'd love to see what you come up with.

Baloth Cage Trap is stupid powerful by choice but Trygon was just too much to include here. :D

Wait. I still have Trygon Predator here. WTF. Oh well...

Stay with me here, I'm only partially kidding, but some of the blue and white artifact matters creatures in unstable seem usable here. Jackknight, Riveting Rigger, and Chipper Chopper could all be printed in black border, they refer to contraptions, but don't need them to be good cards. Do-It-Yourself Seraph could be a cool payoff that could almost be printed in black border. Again, I'm just mulling ideas around while I should be working.

I was considering them (as in Un-cards) but as humour is so subjective I decided to leave them out.

It also helps that I don't want anything to do with the Un-set in any case. ^_^
