Thanks , I do hope these start dropping soon, I am only getting them occasionally from the end reward box after the mission. Played for a while today with venom on and still none in mission. Getting at least one (sometimes 3 or 4  in a good run, AWESOME) in half of my missions when I play the crusader. If I upgrade the Venom card (or any card) does it only raise the overall reward like the card I upgraded went from 50% to 55% for xp, cash, glory or would they also give bigger bonus/chance at finding the item the card gives (tarot cards or shards ect)?
