How can simulation speed be a concern in a turn-based card game?

HearthSim is designed purely as a AI vs AI game simulation tool. It's not a "playable" Hearthstone clone. In the examples on my blog, I usually run 40,000 simulated games per data point, and each set of 40,000 games usually takes a few hours to run on a relatively modern PC.

Because this simulation is concerned with simulating as many games as possible. So overall speed matters.
