Played a bit more yesterday, and a few more interactions came up that we came to quick agreement on, but weren't entirely sure:
Yokuni + Cloud the Mind: Yokuni had already copied another character's ability. After that, my opponent Clouded Yokuni's mind (and I didn't have a let go in hand.) Can Yokuni still use the ability he copied? We went with yes, because Cloud blanks his printed text box, and the ability he copied was not printed on him. The obvious counter is that what's printed on him lets him use that ability.
Gifted Tactician + ?: Sorry, forget the card that was played on the tactician, something that stopped him from taking actions until the end of the conflict. His reaction gives him a card after winning a conflict. So, do you win the conflict before or after the conflict ends? We basically flipped a coin for that one.
