Wouldn't it still be better to use the cards when you draw them until you get what you want? Like if you want to do an AoE balance, but you drew a spire you shuffle and draw an arrow wouldn't it be better to use the arrow instead of Royal Roading it for a buff you don't want? If I'm looking for a certain combo like AoE Balance I continue to draw and use the cards until I get a balance I can hold, then I keep drawing and using until I get an Spire/Ewer.
