This cube has been built around a selection of top picked commons in draft. With that as the base, I’ve selected a handful of archetypes to support to keep the cube concise. Rare picks from Neon Destiny will help fill out the archetypes with cards that can also fit into other decks.

Archetypes
White and Blue (WU-Azorius): Vehicles
Blue and Black (UB-Dimir): Ninja/Rogue Ninjitsu
Red/Green (RG-Gruul): Modification
White/Red (WR-Boros): Samurai
Black/Green (BG-Golgari): Graveyard matters

Note: A light touch of enchantment matters (WG - Selesnya), artifact matters (UR - Izzet) and enchantment and artifact matters (WB - Orzhov) may be added.
