I discovered this myself recently because Amphibious Assault doesn't seem to count as a Special card for the Play 30/60 Specials daily quest, no matter how many times I use it. I've played it countless times over at least 10 games, and it wasn't until I also added Oneiromancy to my Seasonal deck that I at least got to 1/60, which is still a problem since I played Oneiromany twice. I was thinking that maybe it's a problem with the new Master Mirror cards; it's possible that they weren't programmed properly, so they don't count for any of the "Play # X cards" daily quests. But ultimately, this is just speculation.
