if we open all the plates we get all the tailed beasts?
can anyone confirm this?

well i'm wondering to open or not so it would be good if a mod could answer
cause' opening them seems like a good deal for 700 coupons

well ok, i said fck it and opened a set
here's what i got, for people that are interested like me
however not sure this guarantees you get all the beasts every time

all in all, i'd say not bad, was expecting a few more points, but the average seems to be slightly less than 10 points per plate, not counting beast plates
