I'm reasonably experienced playing Agricola - but the family friendly version only, because the people I've played with find the game complicated enough as it is.
I understand how the minor improvements and occupations are supposed to be used; at the start of the game each player will have seven occupations and seven minor improvements, which they'll play through out the game.
The question is - how do I decide which deck (E, I, K) to use, and how do I select nPlayers * 7 occupations and minor improvements from it?
From what I've seen, the purpose of the different decks is to provide differing levels of complexity to game, the E deck being more suitable for beginners and the K deck for very experienced players.
I also see there are various ways to distribute the initial seven cards, a draft commonly being used, as suggested in this question.
Say I am playing with a draft, with three players. Do I just randomly select 21 minor improvements from the E deck?
Can someone please provide a step by step guide to setting up the game, from deciding which deck to use, to selecting the cards for draft/mulligan and then drafting them?
