Four Dozen Eggs is an Action card which can also be sung with a character that costs 4 ink or more (Or Gaston Baritone Bully who has the Singer 5 keyword)
That said, it does fit well into an aristocrats build, especially with the Void trigger
Twice Upon a Time Twice Upon a Time is a decent card in the precon it comes in, but I see it really shining in a shapeshifter deck
I could also see this as a finisher for a Control deck
