One thing I wanted to say about this is that this feeling you have (it’s not entirely incorrect, I think) it is at least partly due to the wildly skewed power-curve of cards in this game, and the designers refusal/reluctance to introduce a banlist.
Many games feel like “find the astro” roulette not necessarily because of some inherent design flaw, but simply because astroscript is an out of control power card that almost wins the game for you the moment you find it. (not trying to pick on astro here; the same might be said at different times of t1 pancakes/wyldside/faust or beginning a siphon spam train before the corp finds an answer). I’d definitely encourage trying different formats - either a cube draft or BB45 - which both help a lot to mitigate that feeling of “there was nothing I could have done differently, I lost this game to pure bad luck.”
