After playing for over a year, and not spending anything, playing each day to do daily, I have to say not a bad pass time, assuming you have time, but it's really rough for new comers which now when get into high ranks they have a bad time, since often they do not know about top meta, and rough decks which will give them a field day, and cry to sleep knowing they got lock so hard they might as well never touch yugioh again because how crazy some of these cards are. I mean all it takes is one card to combo the whole deck, basically you can go make a sandwich, and comes back, and by time you finish eating, your opponent would finally finish their turn 1, just so you can wipe out their whole field with one card, and win the dual, because they spend all that time to bring out their best boss monsters only to watch it get sent to the shadow realm in mere seconds, and if you listen closely you can hear them screaming out of rage.

But yeah great game, thousands of cards that can be unlocked, they're very generous giving a ton of free booster packs, a lot premium gems for free from their events, daily worth doing, as well battlepass which also good since it basically pays for itself, and doesn't take crazy amout of games to max it out, like TBH can max that battlepass within a week if play everyday for hours, but for avg joe that play 1 - 2 duals a day can have it done within 2 months easily, this just casually playing in events, and rank, don't even have to win to fill out the battlepass.
