I'm pretty sure that the
Bloodbraid Elf issue is already taken care of upstream (I discovered a similar problem with
Treasure Keeper and tried to address it). Hmm, I also noticed that the AI has been very reluctant to cast things that said "...sacrifice..." in their additional costs lately, I need to take a look at what's up with that.
EDIT: Looks like cards such as
Natural Order and
Eliminate the Competition now need an explicit AI sac priority list specified for them, which kinda makes sense since we don't want to see the AI sac a CMC 8 creature to go pick a CMC 3, or sac a whole field of CMC 4-6 creatures to wipe off the opponent's CMC 1-3s, which it would gladly do without any restriction in place. I currently added AI priority lists to both specifying that the AI will be willing to sacrifice tokens and also creatures with CMC 2 or less to these cards, hopefully it's more or less satisfactory for now (I guess the AI will still do dumb things from time to time, but at least not as noticeably, hopefully
).
Let me know if there are any other "as an additional cost, sac..." cards that the AI wouldn't cast, I'll look into specifying priorities for them as well.
