Ok, i got confused. Situation:
I play a dedicated buttler and discard a serpent from yoth from my hand to let the butler stay around. It always seemed to me, reading the text from Serpent of Yoth, my opponent has to sacrifice a character. I was told today that this is not true.
But if this indeed is not true why does FFG use 2 different wordings, that is "enters a discard pile" (muddy waters) and "enters a discard pile from play " (arcane hunter). Why add the wording "from play" if it always should be from play?
Also the latest faq mentions that the term "enters play" is an all-encompassing term and does include "put into play". The latest term bypasses all cost and play restrictions. Why should the term "enters discard pile" not be all-encompassing?
If indeed my opponent does not have to sacrifice a character when discarding serpent from yoth after playing a dedicated butler I'm afraid another combo in my deck is useless:
Can I play unbound - discard four characters (which after discarding enter the discard pile), destroy an opponents character with printed skill 4 or lower (using Unbound) and after that sacrifice my professor Nathanial Peaslee by using Ritual of Summoning for example. Then, still in the same phase I pay 2 to get my professor back and also the 4 characters I discarded when playing Unbound. My opponen does also gets his character back which i destroyed with Unbound. It seems to me this must be working. Its a nice combo but it needs two high cost cards on the table (professor and ritual of summoning). Furthermore i have to have an Unbound in my hand and lots of characters to discard. Does not seems a broken combo to me but now I'm doubtful if this is possible.
