Collectible Card Game Headquarters

Clockspinning, for example, needs to know whether it should rate removing a time counter on a suspended card higher than adding a +1/+2 counter to a card on the bf.

Also, for Clockspinning, it should value removing the counters under 'having any is bad' from its own permanents, or the ones where 'having any is good' from its opponent's permanents. Not sure how easy that would be to handle, though, and at least the ranking will keep the AI from doing utterly stupid things with it -- Clockspinning is a complicated enough card that the AI will probably never be able to get it quite right outside of trivial situations.

As current version now, AI Clockspinning is randomly removing or adding counters on opponent suspended cards, so it's already a good thing it can at least cast it and target properly

Just a request, and I don't know if it is possible, but could we allow +1/+1 and -1/-1 counters to coexist?

I was just testing Carnifex Demon after Forgotten Ancient, and when I used the Carnifex Demon it removed counters from the Forgotten Ancient, which 1) doesn't allow Forgotten Ancient's ability to be used most effectively, and 2) means it doesn't have -1/-1 counters to proliferate or remove with other effects.

It's possible but not legal - +1/+1 counters and -1/-1 counters annihilate each other as a state-based action (704.5r), and there's no opportunity to respond (704.3).

Huh, never knew that. Wonder why.

Belatedly: Possibly one fix for that would be to have it give a positive value for -1/-1 counters on Carnifax Demon when it has only one remaining (so it will value adding more if it controls it), and a 0 value otherwise (so it won't add more or remove them, aside from by using its ability.)

But cards that can benefit from having -1/-1 counters are extremely tricky for the AI to manage, and I suspect no matter how it's arranged it will always make the wrong decision under certain circumstances.
