If it's type 1, go without a leader, because Rick, John, Martha and Coby get their abilities fully activated that way
I'd say Eyrik for T2, I prefer him over Hugo but that's just my opinion.
Hugo, Morphun and Eyrik are the best 3 leaders for any format in my opinion (where's it's allowed, obviously)
Eyrik > Ambre. Why take only 2 rounds with a large advantage (and a huge weakness in 6/4 Ambre ) over 8/5 plus an advantage for every round?
