Second, I will address the issue of Orcish Oriflamme - the reason the copy you linked shows up as is because the version you linked appears to be from Alpha, and Alpha had a couple of printing errors showing incorrect information, one of the more famous examples being Elvish Archers (Power/Toughness was printed at 1/2 in Alpha as opposed to the 2/1 it's been in every other edition starting with Beta)
