Huh. A few months back, when I was trying to test Phoenix+Afla interaction, I gave the trainer AI a 30x minor phoenix deck. Using precog, all I could see were these weird Aether pillars with dark marks on them. Didn't think much of it at the time; assumed that it was because I was trying to give the AI >6 copies of a card. Now that it's cropped up again, I'm not so sure :3
