In outcasts I believe Tara would be it, two activations and summoning. Also none of the other masters really get any added bonus to being the leader besides the Viktoria’s, but Tara’s is better in my opinion
Captain Zipp
Earl Burns
Manchu Roja
The First Mate
Iron Skeeter
Bayou Smuggler
Wrastler
Ronin
I figured the ronin and the wrastler would work the strategy while captain zipp disrupted the opponents lodestone model.
As for schemes I would go with breakthrough and take prisoner or assassinate depending on the master.
