Tag Alias: dark_saber -> saber_alter
Because not only one, but at least three games says so. This includes but is not limited to: "Fate/Unlimited Codes (Portable)", "Fate/tiger colosseum", and "Fate/tiger colosseum Upper"
Aboust costume tag:
On a related note, Saber Lily is just a costume (AFAIK), while SaberLion (or Saber Lion) is a completely different character by herself, as noted in "Fate/tiger colosseum Upper". Borne from Tora Seihai, and is a smaller Saber with a will and personality of her own. Her relationship to Saber is that of sisters (as of Upper). Think of an imouto version of Saber or something. >_<
Do "special costumes" get their own tags, like Saber Lily?
I played Fate/unlimited codes a bit, and Saber Lily is just an extra costume unlocked at some point. And as noted with the "alternate_costume" wiki, this should not get a "saber_lily" tag, but an "alternate_costume" tag instead, if we are to follow things as they are.
(tl;dr = remove saber_lily tag, add alternate_costume tag.)
However, since these kind of costumes are officialy given a name (her name changes even in the game, but not the story, moves or even tone of voice) and are popular enough *cough81postscough*, maybe we should reconsider a convention similar to the cosplay one. How that will go, I dunno.
Or we could just leave it be as it is right now, with "saber_lily" as its own character tag, ignore the "alternate_costume" tag, while still tagged with "saber". (We ignore the "alternate_costume" tag for these "officially named" costumes.)
P.S.
(Please pardon the lack of linking, I wanted to post this sooner. Q__Q)
