I briefly checked whether there is a question like this but didn't find anything. If someone knows there is something similar, feel free to point this thread out to me and I'll happily look at that existing one.
Anyway, so there is this question about gaining (it is an even bigger problem in German since translators didn't pay enough attention to the difference between gain and other words for getting a card). Up to now I understood that 'gain'
always refers to taking a card from the supply and putting it (somewhere) in my deck (most often: discard pile). Some cards trigger when I 'gain' another card, i.e. I can reveal a trader when I'm gaining a curse because my opponent played a witch or because I bought one. Or I can reveal watchtower to trash the 'gained' card or put it on my drawing pile.
Now what about graverobber? It says I may 'gain' a card from the trash. Let's say I chose a death cart from the trash. Is it 'gaining' so that I can reveal a watchtower to put death cart on my drawing pile and immediately trash the 2 ruins that I would gain upon gaining a death cart? Or haven't I gained the 2 ruins at all because I didn't 'gain' death cart but took it from the trash? DXV uses
'get' in his secret history to describe what graverobber does.
So, in other words: is 'gain from the trash' a kind of 'gain' such that on-gain effects are triggered or is it an improper word since one might mix it up with gaining and gaining can never be from the trash as it is always from the supply?
(for completeness: in German, 'gain' = 'nehmen' but they also wrote 'auf die Hand
nehmen' for 'put into your hand' as it is said for adventurer ('auf die Hand' = 'into your hand'), leading to a situation that I might look trough my drawing pile until I find 2 treasures (e.g. IGG), 'gain' them (i.e. from the supply, i.e. opponent gains 2 curses), discard everything but the treasure cards and put the 2 treasures that I found in my drawing pile back since there is nothing specified on those cards.)
