Dune imperium 5th/6th player pack.

There are numbers next to the model for how many of each you have to print. This assumes both the Rise of IX as well as Immortality expansions. 

A suggestion for playing with more than 4 players - how to get an extra starting deck?

We put all the starting cards as well as 10 random cards that cost 2 or less on the table (if you're playing a 6 player game, add 20 cards, of course) - each player drafts a card until there are no more left (each ends up with ten).
