Act Three! Everybody Dies!
2. If I use an Fast / Reflex action on a card and it is put back on top of my deck. I then play a card that allows me to draw a card. Can I use the Fast / Reflex action on that card considering I already used it once, or is it considered to be a new card and is usable again?
Otherwise all good enjoying the game!
You've already got your answers, just wanted to highlight #2 here. This is kinda the crux of the game, finding out the combinations that let you play powerful cards more than once, stacking your deck into preferable positions and the like.
When you're able to pull your "discard after use" weapon action multiple times with + damage modifiers, you'll be awfully happy with yourself.
Of course, then you'll see the darkness track move up, but that's for another discussion.
