Two questions, first, what specifically makes them better
As the name suggests, you're probably better off storing these in your collection rather than playing with them, but they command a high price because they're likely to be a limited printing a la Collector Boosters
If this card was Ritual Summoned using "Blue-Eyes White Dragon", when it declares an attack: You can change the battle positions of as many monsters your opponent controls as possible, and if you do, the ATK/DEF of those changed monsters become 0, also, this turn, if this card attacks a Defense Position monster, inflict piercing battle damage to your opponent
We liked the idea that one was more aggressive and one was more defensive
My procedure is, sadly, very sensitive to scan quality
The cards will feature a special Pikachu pumpkin stamp in the corner of the artwork
