I like how in the first game the announcers thought after a key Smallpox they were into a long grind and remarking on what fun the Elves player was going to have next turn and then he drops a Thespian Stage and plays Crop Rotation into Dark Depths and they were like "oh crap, this has gotten ugly fast. this has escalated quickly" .
That was quite amusing. Personally, I wouldn't use tutors like Crop Rotation or Entomb simply because they are combo piece cards and don't disrupt my opponent's game plan. But if it works, go for it.
Three Lilianas to rule them all. One Pox to find them. Smallpox to bring them all and in the Sinkhole bind them!
