Sometimes Schödringer's Cats just staring there and don't use their abilities, even if they have a lot of quanta. They work only occasionally.
AI play Liquid Shadow too randomly; for example, it uses it on its own Pest which has 0 attack (?).
In my Arena deck my upgraded Blue Nymph appears to be unupgraded (Nymphs weren't given by Oracle).
