I myself personally dislike matrix energy. I love the EM ones design, but I think that the 1 in 3 or so that matrix energy comes in, should be replacing a common card, not a reverse holo, by making it 1 in 3 your making the cards that ppl want harder to get in RH.
The following cards are hard to get since they made the set with Matrix Energies
Rare Candy - EM, HP
Holon Adv. - HP
Holon's Casty
Battle Frontier - EM, PK
Scott - EM, PK
Stevens - PK
It really does drive the price for RHs up, which is bad cuz it also makes the rarer,
Here lets take a look -
Lets say that there is 100 RH in a set (I know there is only 91 in PK but bear with me)
I open a set with no energy (or unown's) just the RH's
I should get a full set in 3 boxes plus have 8 rh left over if it works out well
Now, lets take the set that has 12 per box for matrix energy
I will open 4 boxes and I still wont have 100 rhs, I will only have 98, which means in the time it takes me to get 100 rhs in a non energy set, it takes me more than 1 box more to get it from a energy set,
I personally hate it. It makse me very frustrated.
JMO Tho,
