This seems like a good upgrade if your seeker can cycle their deck quickly to redraw them after shuffling them in. The potential for an extra point of damage could be useful for odd-hp enemies, and if not needed you either get to keep an extra card or get an extra resource.
Also of interest is that this card has lost the text "When Occult Lexicon leaves play, find each of those copies of Blood-Rite (even if they are out of play) and remove them from the game." I think this means you can now swap the tome out after playing it and still keep the Blood-Rite cards in the deck. You don't get to use them as powered up versions, but replacing it with a better hand item might be worth the trade.
