The Cards Explained section in particular has too much information too early for a new reader to properly digest. It would work better to have each type of card briefly introduced (what you have now with each card's caption would work well), and then move the detailed effects of each card to after the section on Game Play (and maybe even after the section on Ego Battles). The Colours section seems to be redundant to the set up information under game play and could be eliminated. In all, I'd recommend you:
-- Expand "The Deck" to contain a sample and brief description of each type of card
-- Follow that with a "Set up" section that combines the information current under "The Colours", "The Play Area" and the beginning of "Game Play"
-- Then "Game Play", "Ego Battles", and finally
-- A section with all of the detailed effects of the cards.
