Thanks to the Haunter Tower, this unlock was a breeze! I went through msot of the event per normal, but the Haunted Tower provided so many skeleton hands that it was just some spins and boom, 5-star!
One thing I learned from this event so far, my Marsupials need lots of work. Taz Maniac is my strongest, he has almost half the power, and I only started on him last week. Hoping we see some battles where Tasmanian toons are used, several of my Pirates are in the 50k range.
The only ones I use on even a semi regular basis are Dark Matter, Warrior Princess, Conqueror Taz, Tazinsky (and only recently for anti-dodge), She-Devil (stall on Magic team) and Banshee Devil (but not overly impressed or unimpressed). The rest I pretty much never use! :)
