My personal suggestions for some card fixes are:

Royal Road decreases the next Draw recast to 15 seconds.
Putting a card in Spread reduces the chance of it being a Draw Card. (Imagine we have only 2 of each card in the deck, so taking one out would reduce the chance)
Shuffle reduces the chance of it being the Draw Card. If the Draw Card and Shuffle Card are the same, there is a 0% chance of Drawing that card. (in other words, Shuffle and Draw takes both cards out of the deck)
