On the discussion of multicolor cards, I was thinking about multicolor packs that others can draft as the final 3rd pack (cuz 3 jumpstarts makes a pilotable 60 card deck) where the player either chooses a multicolor pack. Or they randomly get dealt one of the multicolor packs: so if someone is izzet then from 3-wherever izzet packs they are randomly dealt 1 of them.
You could also go the direction of a utility multicolor card draft after everyone gets their two packs where people switch a couple cards for multicolor cards (but that will take longer than getting a whole pack).
Only major downside I see for both of these options is if someone gets a 1 color 40 card deck.
To me I would think that would make the utility draft cut off from them since it'd likely result in color screw.
For the other option, not sure if you would want them to splash for multicolor pack (likely fine if mana base is good) or if you just give them a 3rd non-multicolor pack (likely of the same color to keep against color screw).
You could also rectify this by the option that players never get the same color twice for the first two packs, which could level the playing field for all players. That will definitely make things a bit simpler (but I would be sad cuz I would want to see all the synergies).
Slightly off-topic, but does everyone agree that 3 or more of the same color mana on cards is probably a bad idea for jumpstarts? I'm looking at
necro-impotence and I'm not sure if I should do a jumpstart with it.
