Crackdown and noetic scales shut down many decks and become cards that you answer or lose. I may add noetic scales if all the creature cheat decks become too powerful but I can only see Reanimator being a problem. Reanimator is easily nerfed by changing the mana cost of the reanimate spells.
Verdeloth was included for the big ramp deck but I feel hornet queen would also be useful in that deck along with others. The inclusion of hornet queen means green is less likely to need wing snare as a sideboard card.
Juggernaut doesn't really have a place in aggro decks as all colours have better 4 drop options or the aggro deck wouldn't want a 4 that dies to most removal. For some reason I thought it had trample which would have made it much better. Aeolipile is a fine removal spell for colours that don't have access to it. Temporal aperture is a unique effect for the cube and seems like a fun include for slow decks.
Most of the cards added are featured in similar cubes but were omitted from mine. I've removed the sisay package to make room for some of these cards. Instead WG will be encouraged to go wide or big with Asmira and Mirari's wake in the gold section.
Some of the includes do not have clear swaps so I have just added them but I will remove 10 at some point in the near future.
After listening to Lucky Paper Radio's episode on their new Neoclassical cube, I've been reflecting on some changes. They mentioned that tutors in restricted environments allow for more niche decks to work due to lack of card density. They also pointed out that the era of older cards was dominated with powerful cards that required you to build your deck around them. I have added some cards that I think fit this bill which should give a different thing to consider in drafting.
I have changed the ub artifact deck to a mill deck. The artifact deck was quite parasitic but powerful. The mill deck is a typical UB control deck with the plan of grinding its way to victory.
The artifact focused deck is now WR. This works because both these colours have mono aggro decks so the artifact deck won't stretch them as far. The colours both feature land destruction to synergise with the rocks. Goblin welder combos well with several artifact creatures by reseting their downsides.
Stupor is the worst of the discard spells so it mostly goes to sideboards. Oppression was in the cube for the RB to make the discard not as relevant. However the RB decks I have drafted don't have enough creatures. Instead I've added some generically powerful creatures. Nether shadow's upside was tough to get going so Brood of cockroaches' ability will likely come up more often with sacrifice or board stalls.
With Momentary Blink now being in the cube, 3 of the multicolour cards could be played in any white deck which felt a bit imbalanced. Goblin legionnaire is a solid creature for WR. Tidehollow Sculler can get a removal spell out of your opponent's hand that could deal with your reanimated fatty.
