These are cards from the fire emblem cipher (0) series .b17 is the 17th booster release and is called "the advance of all heroes".

All cards are in Japanese. The rarity is also a little different it goes

N = normal 

HN = high normal

R = Rare

SR = super rare

On occasion you can get R+ or SR+ and signed but none are here sorry.

They are all brand new from pack to soft sleeves.

All will be sent out in toploaders to avoid damage during transit.

Questions welcome 

Thanks for looking.
