^^^ In this box, there are SEALED items. ^^^ This box unseals those items. Giving them there stats back I believe..
You just had bad luckkkkkk. I didn't even get a timed, went straight for the perm and it was less than 20 boxes. Actually I might of had a decent luck there, idk 200 boxes though is definitely bad luck though for sure lol
You obviously weren't on RF when the boxes first came out on GC. I think it was 8 hours of non stop mega spamming of GC items. The first 3 hours of mega spam, NO ONE got shadow ninjitsu. Call yourself lucky. If you have avalon with stuff like Critical Double, you'll know that the rates of hitting a critical double is literally 2x-5x higher than getting a perm rare from a box.
