Drawing the right card in the middle of a duel when you need it the most dang that feels good.
Oh yes yes yes! Then it lets you win the game! But it is really rare.
If I am not mistaken most anime shows that have card duels in them have episodes showing this happening.
I remember my mates quoting yu-gi-oh lines (even if we are playing MTG) while praying that the next card they'll draw from the pile will be that winning card. It doesn't happen. hahahahaha!
