Against platinum arena, the AI did the following move:
Played Fate Egg. Played Shard of Readiness on the fate egg. Hatched the fate egg into a pair of graboids. Then, it evolved the first graboid (the one that was in the previous egg slot) which it should not have been able to do. This will be a very hard one to verify, and the screenshot doesn't really prove anything, but I included it anyway to aid my explanation. I don't know if it would have evolved the second graboid as well, but it didn't have any more time quanta at the end of its turn to try and do so.
