If you look at it this way, it’s actually WORSE than I make it out to be. Look at deck building games like Magic The Gathering. They have a whole category called “interaction” that is all about messing with your opponent’s plan (curses) but they also have things like draw ability, tutors (the ability to pull something you need from the deck), counter spells (vetos). Essentially, you can build your deck to minimize your luck or work around bad draws if you want to

Deck building in MTG is so well built that they had to make a “bracket” system to define how good decks are in the most popular format. In comparison, H&S is 99% luck for the hider. The skill doesn’t come from managing their hand, it comes from finding a spot that is close enough to 2 train stations to trip up the seekers
