I just grabbed the final cards I needed for my Isu, the Abominable(comments welcome!). It started out as a yeti-themed deck but there just wasn't enough to keep it going so it morphed into a pretty standard snow deck I think.

I am definitely looking forward to trying to get the Thespians Stage -> Dark Depths combo off at the table!

May try again with the yetis in another deck. Not sure it would work, but the theme in my head is "hunting yetis" where you have yetis for beating folks with and other cards creating clue tokens. But yeah, not sure about the synergy yet...
