I haven't succeeded a single one since I started this game except those freebies ... even Naginata which should be acquirable didn't work out for me...

I don't even want to keep track as I don't look forward to get one anymore - whenever I see one I'll just automatically think "well ... 30 summoning points"

Zynga should make them more easily acquirable the higher level you are -  they are kinda useless anyway when you're high level with (likely by now) better cards too :/
