Some people chose not to craft BTE in advance of the suspension, because it was not a ban. When BTE is eventually banned, will those people get a chance to craft the cards and get wildcards at that time? Or did we miss our chance due to this "bank error"?
This will work the same as Fires or Agent, which were first banned in Standard, then later in Historic: People who got the wildcards before won't get them again if BTE gets fully banned in Historic, and people like yourself that didn't get wildcards in this (mistaken) case will get wildcards for any copies they've collected by that point.
