Help me please33

My friend who plays Nyanko told me that Giant Zeus is a guaranteed draw and the series is good, so they spent 3000 cat food and got 3 ultra rare cats: Skanda, Isis, and Aphrodite... Currently, my friend is stuck on Chapter 2 of the Cosmic set, called 'Big Bang', has cleared the Future set, and is stuck on the Legend Story stage 'Connecting Heart and Body'. Are Isis, Skanda, and Aphrodite any good?
