So with the best of my abilities I still cannot determine correct way to play if a player plays a Necromancer to play a Mining Village card from the Trash pile.
By "... simply doing exactly what the cards say...' it seems (a horrible assumption it seems when asking a question in the forum, but I am going to ask anyways), that a player would get "+2", because I could not find a ruling that said where Trashing could not happen from the trash, although 'Trash rules do state '... Trashing a card usually means removing it permanently from your deck...' but then again the word 'usually' is there, so thus my question to clarify if my question.
Re: Necromancing a Mining Village?
The rules for Mining Village itself make clear that you cannot trash a Mining Village that is already in the Trash.
Also, that you do not get the +$2 unless you trash it.
Necromancer can be used on a card that trashes itself when played; if the card checks to see if it was trashed (such as Pixie), it was not, but if the card does not check (such as Tragic Hero), it will function normally.
