r28725: Cards that modify the rules in such a way that it's impossible to attack with more than one creature (e.g.
Dueling Grounds) currently break the AI - e.g. if I have
Dueling Grounds on the battlefield and the AI opponent has three creatures it'll try to attack with all three (there will be an attacker icon on all three creatures) and will fail, thus attacking with none, but the attacker icon will linger on the AI's creatures even past its turn and even past my next turn. This holds true for other cards with similar effects. I'm not sure but it may also hold true for other attack declaration limitations imposed on the AI (haven't tested, but may be worth keeping in mind).
