On closer inspection, the banned list for Commander in Magic Online, which actually is official, appears to simply be derived from the banned list on the EDH site. The DCI-sanctioned list is missing Black Lotus, the moxen, Time Walk, and Ancestral Recall, presumably because they were never released for Magic Online, although I have no idea if that's even true (I don't play Magic Online). The list on the EDH site is missing Lion's Eye Diamond, presumably because it hasn't been changed in a while and someone found a way to break Lion's Eye Diamond in a highlander format (maybe with the Bomberman engine or something like that, although it seems rather farfetched). and it turns out that, according to their changelog, LED used to be banned on the list on the EDH site, but was unbanned. For some reason, the DCI list still has it banned. Anyway, the two lists are pretty similar either way. I still don't know which one Ransac is saying he's in favor of (because one calls itself "official" but isn't really, and the other is official, but is only for Magic Online, but is ripped off from the not-technically-official list anyway).
Of the two lists, I guess I'm in favor of the one on the EDH site, which I quoted in my post #203.
