I just bought Warhammer Invasion last night and am at a loss on how to get started with the deck. I have the cards sorted out into the 4 different groups, but I also have a ton of cards for quest and support and what not left over.

How do you incorporate the quest cards into the game as you play? What is development?

I am more at a loss on how to use all the cards properly, I don't quite understand how you would get the quest cards into the game unless you shuffle them into your deck? or do you have your deck and your quest cards in a pile and set them off to the side and draw from either one depending on how many power tokens you have?

I am just not sure how to start this off properly. I have watched the videos for the how to play part, but it doesn't really explain the separtation of the cards and how to incorporate the quest elements into them.

Unit cards, Support cards, Tactic cards and Quest cards are all in the same deck. You play a quest card like a support card or unit card during your capital phase.
