It really depends on you though, no matter what everyone else says. I got my best
survivor finish (12 wins) running an 8 card
Ulu Watu +
Ambre deck. I don't have it on preset but it was the 4 main 5 stars (hiki, tan-man,
Lulabee, and
Stanly) with
Shayna,
Buck,
Wee Lee and
Zack. Now most people would say I shouldn't have had
Zack in there, but I wanted to carry some SoA just in case, and he definitely saved my bacon during the run for 12. So really it depends on you. If you like playing
Python that much and you're comfortable playing him in a T2 setting, I don't think you're wrong for playing a 9 card deck.
that being said, in THAT deck, I'd drop him
