RE: Booster Boxes
I don't know if parents would buy booster boxes for kids. They might buy a couple of packs, more or less depending on if they think you're really passionate about the playing the card game and entering tournaments or if it's going to waste their money and you're not even going to keep them or take good care of them.
I know my parents would have never bought me a booster box, they don't think it has any real value to it and think I'll get bored of them eventually.
I personally don't think it's worth it for a booster box nowadays because I only collect, and ultra pull rates have been so hit or miss...
You can try to convince your parents but if not I say ask them for enough money to buy the cards you really want. A lot of the singles are pretty cheap. None of the really rare cards in Phantom Forces are worth over 40$. If you really set your heart on getting some packs but your parents won't buy you a box, go to your local comic shop or Gamestop and buy the packs there. The reason being is that, they are .25 cents cheaper most of the time. Five Below is doing a buy one get one 50% off though on Black Friday.
AND LAST BUT NOT LEAST... here are my reasons I wouldn't buy a Phantom Forces box.
My friends both got boxes.
Box 1 (value of cards 50-60$)
Full Art: AZ
EX: Manetric, Gengar, Malamar
Holos: 5
Box 2 (value of cards up to 40-50$)
EX: Mega Gengar , Florges, Aegislash, Dialga
Holos: 6
Now here's why I would buy a box from this set...
Secret: Silver Dialga (about 30$)
Full Arts: Gengar (15$), Florges (9$), Xerosic (12$)
EX: Florges (5$), Manetric (15$)
Holos: 5 (up to 5$)
Overall Value: almost 100$!!!
