I think those cards are just used because we don't have enough alternatives. Honeslty I very often thought about not taking wind because it needs a free slot in my card deck. Their could be lots of better cards for theme decks for example.
Take the uncommon cards for example: Last hope gives you at least 1 stock+ for free... but it's not in every one of my decks because ( depending on the strategy ) there are better cards to take.
