I'd rather trust something that rarely fails me, but yeah debuffs against wind disaster make things go faster.
I don't consider putting any money in this game (or any gacha game in general) a good deal, that's why I am f2p. But that's beside the point. If you have a chance to play the game of "pay 10 dollars, roll 6 on dice and win 20 dollars" and you "trust the heart of the cards" and play it, then you were not scammed (or technically you were, by "heart of the cards").
