Ok, I'm done with a first reading of the rules. Everything seems more or less clear (still, I think they could have been written in a clearer way, but anyway), but a point keeps on slipping through my mind: let's say I draw an Event card and have to spawn the Genestealers. The colours istruct me which terrains I have to spawn the Genestealers to. And I'm fine with that. Then (pag 23 of the rules) they say "the current player takes three cards from that side's blip pile and places them on the position containing the yellow Terrain card" . How am I suppose to know which side ? I mean, how do I choose to draw cards from the right or left blip pile?
Thanks for help
