The widening of the pool of drafts doesn't work because it is not fun. When you find something that works you want to use it as much as possible because as the player all I want to see is the numbers get higher and higher. This is where the fun is. Most of the additional drafts aren't fun. Some I never use. When I play I don't even care about the forces that make it harder at the start anymore because most of the gameplay comes from what cards show which is heavy random number generator. There should be a continue play button when you fail the run though just so you can keep playing and see the numbers go higher and higher.
