I also have some problem with the Ai when using Ghostrick cards. It can't seem to know that it needs to set it facedown when there are no faced-up Ghostrick cards on its field.
What do you mean? The game mechanics prohibit Ghostrick cards from being normal summoned when no face-up Ghostrick exists on your side of the field. In this case, available Ghostrick cards shouldn't show up in the normal-summonable list and they should be set instead by the default set logic, if not specifically coded otherwise.
~~ about fiendish, lance, maxx 'c'
I found someone (can't remember his name) who coded the cards manually (brute force) and I tried using his AI. Crazy, but it works correctly like 60-70% of the time.
My latest updates include Veiler, Maxx "C" and Breakthrough Skill. No Lance or Fiendish Chain yet.
I don't think Sebrian has added those fixes to his latest uploaded test version yet, though. You can download that version in
this post, and it will most likely be included in Sebrian's next test build, which will hopefully be added soon.
