And Yorick applies a multiplier that goes up by a whole number with every 23 cards discarded, which can easily happen every round or two when you're winning rounds in a single hand.

Flash Card was the weakest part of the loadout; it was a replacement for the Neko card I got just before getting the Vampire card. The Neko gets more multiplier every time a magic card's luck power procs, but the Vampire eats the magic before that.
