I think Mindy is a better choice than Trash in the event your playing style is conservative.
Trash is good, but the Equaliser has some limitations with the minimum being 5. When facing All Stars or other power reducers not to mention 3 Star cards who could reach 10 Power are going to cause problems.
Mindy is vulnerable to Raptors, but a good choice. Personally I would also use Tariel as a substitute, but I would not really put them both on the same deck unless constraints in EFC otherwise force me to do so.
At the moment, in terms of base stats, I agree Zip is the best. My concern are cards such as Lois Ld, Duchess, Djet, Dashra and Dominion but a good card in the face of Equaliser and SOA.
