I agree with this idea of Haley on paper, which is why I built her with stealth like most others are doing. The thing is, this deck has tons of card draw AND Haley naturally needs lots of card draw. If you happen to not have 2 same targets in hand at the start, you are fairly likely to have a diesel, QT, Astrolabe, or Symmetrical Visage at the start. Turn 1, click 1 Diesel is probably the most common opening play if you have it. On top of that I slightly modified the standard Calimsha Kate build to have a few more free/cheap installed cards.
As I stated in a previous post, trying out prepaid in Haley like this isn’t an attempt to spam her ability. Doing that I think is possibly the wrong approach as instead of running and doing cool shapery things, you end up being too focused on drawing and installing cards, and then losing. This is an attempt to determine if saving a handful of clicks over the course of a game is a larger benefit over saving 10-15ish credits during a game. I think it might be, especially due to the added benefit of a boost in speed during the early game.
Maybe I’m just flat out wrong and it’s not better, or maybe it’s one of those non-obvious situations and you don’t see how good it is until you take it for a spin.
