Hello,
looked in the game book but it isn't defined. In GSF a card that you are playing is counted as being part of your hand or not ? Asking, because the definition isn't always the same depending on the game (in Pathfinder Card Game by example it would be). I am asking about the dwarf booster that count the number of boost in your hand.
Ike.
I don't have a solid rule citation, but I believe that once the card is played it is no longer considered to be a part of your hand. I'm going off of my general experience with card games more than anything, but I'm pretty sure that's how it works.
Also, the title of this thread would make for a great thesis statement on the analysis of a "hand" in card games and how it has developed over the years.
Cards in a pile face down. Draw deck.
Cards face up in a pile. Trash.
Cards face up on table. In play.
Cards drawn but not in play, generally held in your hand. Your hand.
Cards in your hand can be played, or discarded.
Cards in your hand cannot be destroyed.
Cards in play may be active, activated, or destroyed.
Cards in play cannot be discarded.
It is not considered in your hand.
Discard? Destroy? Trash? What are these strange and mystic words? I only know of recycling and scrapping 
Nice definition, should have been in the rulebook.
Because in some other card games :
Cards in a pile face down. Draw deck. (actually in GSF it is face up).
Cards face up in a pile. Trash. (You mean scrap ? you sure they are face up ? In GSF it is the draw deck that is face up)
Cards face up on table. In play. (Depend on the game, in PAGC thoses cards are on display)
Cards drawn but not in play, generally held in your hand. Your hand. (This one clear)
You still didn't answer :
Card being currently played while I still reading its text while physically having it in my hand. It is not recycled nor trashed yet as I am currently applying its effect, is it hand, is it limbo ?
This is the sort of clarification that is required in a card game because for some it is part of the hand, for some it is not.
I'd say that if you're in the process of applying a card's effect then it's in play - if it was in your hand, you wouldn't be applying its effect, and if it was in the trash/scrap, then you'd've already done that and finished with it.
