Re: Who are "Suyin" and "Wuming Sisters"
Ok, apparently I was reading an older version of the ThunderGryph rules. (Which I think that I got from here at BGG a few days ago, but it seems to have been deleted from BGG.) Anyway, the rules file available from ThunderGryph's web site looks newer and shows two additional characters whose abilities are used prior/during the draft. I'm guessing those are Suyin & Wuming Sisters.
Wuming Sisters: 1) At any time during the drafting phase all players must draft an additional card. 2) Can only be used once but can't be used if it causes the players to draft a sixth card.
Suyin: Take three random character cards that were not drawn this round and choose one. Fushen will become that card.
But since the newer rules indicate 11 characters, and I've got 9 in the Big Fun version and these 2 are new, I'm assuming that the second one is Fushen and Suyin is one of the 9 original ones that got renamed from the Think Fun edition.
So, mystery is solved. (I think.)
