This is my first cube, feedback is very appreciated. This started out as a multi-color big-dumb-card-cube, but I'm now trying to focus more on synergies.

Rules:

3 packs of 21 cards, 2 picks per pack
Planeswalkers can be commanders
Mono-colored commanders have "Partner"
Hybrid mana can be used in decks with either color.
Cards that reference another specific card (partner, meld) are drafted together.
Life total starts at 35
Ninjas count as Rogues
