UN-G100
Hi y'all! Created for this 360/100 contest over on Riptidelab, the UN-G100 cube features only 100 unique cards, so expect a lot of duplicates! This primer will get you up to speed with the quirks of the format.
Because the nature of this contest heavily restricts variety, I wanted to cut one color to create some breathing room within the colors I did want to support. This wasn't actually the first time I thought about cutting a color, as I believe there are some merits to do so in the context of cube. For example, eight, the number of drafters in a full draft pod, is divisible by four, the number of colors remaining after you cut one of the five colors of Magic. For this cube, I chose to cut green. If we look at the core mechanics of green, almost all of them can be found in other colors except for ramp. However, ramp is hard to do right, and often it feels like a trap, leading to games where you draw either your ramp spells but not your payoffs, or the other way around. Sorry green, no hard feelings, I hope!
With green out of the way, I wanted to pick a four color card as the figurehead for my cube, and since Yore-Tiller Nephilim is a bit lame by today's standards, I chose Breya, Etherium Shaper. From there I explored a heavy artifact matters theme that pervades the entire cube. No matter what color you end up drafting, your deck most probably will have a heavy artifact component. Drafting this cube, however, you will find that doesn't really narrow you down to any specific strategy. You can draft lightning fast aggro decks, grindy midrange decks, and removal-heavy control decks, all of which are supported by a plethora of grey cards and tokens.
In addition to the artifact-heavy component, I of course wanted to play with the color disbalance. Both prismatic decks and monocolored decks are supported. If you draft three or four colors, you will be rewarded by a suite of prismatic cards, like Prismatic Ending, Painful Truths, and Radiant Flames. Pick your Prismatic Vista's high, because there's only 24 of them in the cube! In addition, you can rely on Chromatic Stars to further fix your mana. Remember, since there are no Forests in the basic land box, the six Stars in the cube are your only way to unlock green mana for the full effect on a small handfull of converge cards!
Monocolor drafters, on the other hand, get their own rewards. These come both in the form of hard to cast but powerful CC and CCC creatures in all colors, like Leonin Relic-Warder and Benalish Marshal, and cards that actively reward you for running a boring but color screw-proof land suite in blue and black, like Vedalken Shackles and Korlash, Heir to Blackblade.
I have playtested this cube a bunch, and it's honestly been way more fun than I could have ever imagined. I encourage you to dive in and see what it has to offer for yourself. Have fun, and thanks for reading!
