Hancock can blame carelessness and coincidence on her actions at Marineford and Sabaody. As for Doflamingo, it's not voice related. He was able to take control of Jozu without muttering a word, and Atmos wasn't drawn in at all. My guess is that it has to do with his control theme, but less literally. Given his connections, he has access to just about everything he could ever need, including information. Personally I would have gone with a chess theme for him rather than cards. He knew 3 things: Luffy and Ace were brothers who loved each other dearly, Luffy was in an alliance with Law, and Doflamingo was in possession of the Mera Mera no Mi. A better name for it right now would be the Barter Barter Fruit. My guess is that he is going to use the fruit as a hostage as a way of dissuading Luffy to continue the alliance. Depending on how strongly Luffy feels about it, things may or may not get interesting. Lastly, Law would have no reason to take out Luffy's heart, and you would think Luffy or someone else would see the hole in his chest when he took his shirt off.
