As pc gamer (and new Deck owner) i’ve started to check any good game deal, mostly x games on Steam but not only. I’ve soon realize that there are great site like Humble to use to buy keys for cheap, but also “shady” sites with very low price who apparently sell non working keys or try to scam you. Did we have a list of the “Safest” site where buy games???

IMO not a great option for Steam Deck. It’s certainly doable, and excellent for PC, but it’s been too much of a pain to run on Steam Deck.
wdym, pretty easy through Heroic Launcher. I have GoG, Epic and Amazon Games working great on it.
Just use it for the purchase and let steam manage the deck chairs.
I find installing via Lutris works most of the time for most games. Definitely not as clean or easy as going through Steam, but it’s typically not hard enough to avoid entirely.
