Originally designed for Pack Wars(1 pack with 10 rainbow basics shuffled in without looking). Expanded out to 1v1 games with
drafts or sealed of 4-6 people. Does not include Library searching, milling, or forced discard except in a few exceptional cases.
There are a few home rules
The cube uses a rarity system for collation. Packs for draft and sealed consist of 9 "Commons", 4 "Uncommons", 1 "Flex", 1 "Rare",
and 1 "Mana." We may be transitioning to 8 "Commons", 4 "Uncommons", 2 "Mana", 1 "Flex", and 1 "Rare." Commons are generally lower-impact cards with some build arounds, most spot removal is here. Uncommons are mid-impact and stronger build around cards, most board wipes are here. Rares are high-impact, must answer cards for the most part. Mana is for lands and other cards whose primary goal is mana production and fixing. It also
contains cards that don't work in the pack wars format, like things that search libraries or don't work without being drafted. Flex is where things that don't fit anywhere else go as well as all tri-color cards. It tends to be mid-igh-impact somewhere between Uncommon and Rare.
For pack wars itself you shuffle 17 rainbow lands(they have all basic types and enter untapped, I often use basics with the back face showing) as well as 10 Commons, 10
Uncommons, 1 Flex, and 2 Rares together without looking at them.
The major themes of the cube are lifegain which is primary in WB, +1/+1 counters which is primary in GW, BG, and GU, and spellslinger(instant and sorcery payoffs) which
is primary in UR.
Minor themes include mono black payoffs, multicolor matters in GW, punisher effects primary in BR, card draw in GUR, artifacts matter in WUB, and planeswalkers in all colors, but primarily red.
There are around 4 multicolor cards(including lands) a pack on average which encourages playing a lot of colors but there's also a
lot of high devotion to encourage running fewer colors as well as some mono color payoffs mostly in B. The goal was a kind of Ravnica experience where there's a ton of multicolor and you're encouraged to play at least 2, but you're encouraged to play as few colors. So 2 color decks are the default with small splashes to a third not uncommon. Green has the fewest mono
color cards but also has the most powerful fixing (which admittedly is still weaker than most cubes). Due to this the recommended
draft format is 4 packs of 16 as detailed above where you remove the last 4 cards left in each pack from the draft, this significantly reduces the pressure to run more colors and helps get much stronger more focused decks. The ability to do this on CubeCobra is upcoming.

W: Aggro/Lifegain low-mid support
U: Control/tempo, mid support
B: Lifegain/Control/Midrange, highest support

UB: Artifacts, low support
BR: Burn/Punisher, low-mid support
RG: very low support
GW: +1/+1 Counters/Lifegain/Multicolor matters, high support
WB: Lifegain/Control, high support
UR: Spellslinger/Control, high support
BG: +1/+1 Counters, mid support
RW: Equipment, low-mid support
