One critical improvement. Make a half deck of Bertha, Shazam, Piotr and Daqun/Erpeto and use a second clan with them. Just because their bonus is useless after the first hit, and you don't want to go for the rest of the fight with essentially no bonus.
Invest in a shazam, you can get a pretty good half deck from bertha shazam bogdan and olga if you got the clints
What would be a good clan to use for the second half?
Something attack manipulating. Saks, Junkz, Huracan, etc.
^ Sakrohm is good because of their defence potential.
