I like the changes to Shuffle -> Redraw but I would like for them to change Royal Road and Spread while they're at it:

Royal Road: Return the currently drawn arcanum back to your deck to enhance the effect of the next card. If no card is drawn, return the card on your Spread instead.

Spread: Add the currently drawn arcanum to your spread where it is kept indefinitely. Execute again to use the card. You cannot Draw the same card currently in Spread.
This change would allow us to manipulate RNG better and making dead draws less consistent. Not by much, but it would be a great improvement to the current system.

It would also be consistent with the new Redraw, since the ability seem to imply there is only 6 cards in your deck now. So why can you draw a same card currently in your Spread? Makes no sense to me.
