My Zeus and Noah Dragon clears from my Mantastic and Fantastic account. Both runs killed the Radar Dragons very quickly and should provide some inspiration on how to deal with them. I have been having a challenging week, but content should begin to flow out once again.
Lakshmi vs Zeus Dragon
Myr vs Noah Dragon
Hopefully these two clears showcase how to efficiently deal with this set of One-Shot Challenges. Many teams are capable of clearing them and I would like to know who you used.
