Do AST really need this Buff?

Ok yes it is good to hold it but what happens in 30 seconds when you draw again? If no one needs healing and you don't have a good card you will either have to RR it or risk overwriting in hopes for the damage card.
Another way to look at it is if you're getting useful buff cards you may not use the Lord and the Lady much. You're not going to throw away guaranteed buffs on a 50/50 chance you get what you want. This gives you somthing to do instead of wasting a draw, which can suck if you get a bunch of useless cards in a run. People act like you're going to use the the Lord and the Lady every 30 seconds.
