Mono-white cube with 200 cards in it. Meant to be drafted in 3 packs of 8 cards, with 8 players. Players end the draft with 24 cards and must make a 40-card deck using... well, basically all the cards they drafted, save maybe one or two. Every card drafted matters.

Cube themes are that of opposition; primary archetypes are opposed by secondary ones.

Counters are kept in check by tokens.
Combat buffs are kept in check by lifegain.
Tapping effects are kept in check by untapping effects.
Removal is kept in check with recursion.

Secondary archetypes do not win games by themselves, and require support from a primary archetype to work.

Subthemes include Enchantments, and Choice.
