1: Truth or Dare isn't considered gambling.
2: Yes, I am on one of the "My Little Pony: Friendship is Magic: the Gathering" cards. Same goes for my friends, Princess Celestia, the Elements of Harmony, just way too many things than one can simply post.
3: Fluttershy just wants to get closer to nature, and I think there's a spell for that, but it's a little risky to perform.
4: I think I'd get another owl to keep Owlowiscious busy.
5: I said don't mention it again! No one breaks a Pinkie promise!
6: Rainbow Dash's flight and speed advantages ensure that she will win..and have a slight chance of killing Applejack, in the process. I wouldn't even think about it if I were you.
7: "The Great and Powerful Trixie" just wants to prove that she is the best unicorn in all of Equestria so everypony would pay attention to her.
8: Pinkie Pie had plenty of spare time, as well as the materials and know-how, to build her Party Cannon.
9: Derpy Hooves is just so...derpy, trying to help out, but hinders instead of helping. I can use my magic to cure her unusual eyesight, making it so that she can help much, MUCH more than she hinders. If she met Discord, he'll use his magic to discord her, being unsure if it worked because there's basically no change in color. Also, when she gets home after being discorded, she'll see the picture that her daughter, or son (I forgot), drew for her, and tear it apart, spreading the discordance to her young.
10: I don't have a very good taste in music, so I'm not sure.
11: Diamond Tiara is just too bratty for my taste, and this is a kids show about love and tolerance.
