No, the objective (at least mine ;D) is to find whether these "normal" Japanese 4th Ed. WB cards are extremely rare or not. They seem to be. I'm starting thinking they have only been released in the booster packs that were in the Rivals Boxes.
As you know,they were 2 Boosters in The Rivals Gift Box
and a Rule Book,it will be interesting to compare it to a
Normal 4Th Edition Japanese Rulebook.Regarding the
fact that WB may have been only in Rivals Japanese Boosters,I seriously think that's not logical,meaning you could get a Stone Rain only from Rivals Gift Box,what about Starter 4th Edition WB,or normal 4th Edition Japanese Booster.Otherwise that's mean 67 different
Cards from Rivals and 311 that you need to get from 2
Boosters from Rivals Gift Box,that's a lot of Gift Box to buy to have a Complete Set of WB Japanese 4Th Edition.
Probably the most Expensive and Rare Set In MTG History Â ???
PS:Ralph ,I guess you have to process my 67 Japanese Scans ;)
