I dont see why you couldnt get past 10 victories with that deck, but dont think of yourself as a bad player because you struggle to use it. Getting 10 victories in survivor is hard Imo and maybe the clan Bangers isnt your cup of tea, try using a different clan or as you said before, change Fifty to another card because he seems to be the weak one there, although you do need an SOA.
So yeh just pratice with it, try getting as far as possible and you'll end up with a winning streak.
Well i would be surprised if people could get 10 victories or more with that deck...
the deck itself lacks a defence making it prey to Ambre/Ulu Watu combos and also is needed for later rounds.
there could be many issues as to why you can't get 10 victories.
for one you might be overpilling too much (which is a common error that i see from most new players in survivor)
6 pillz in the opening for example isn't a smart idea
play bookline and your opponent should follow suit.
e.g you start with blaaster at 1pill
your opponent plays Uranus at 0pillz
It is easy predictions like that which should get you the win every time.
as for the deck?
get your hands on Uranus and graks for they are staples for type 2 survivor and slot them in your deck
slot them in over Lennox and Fifty (however Fifty can be very annoying in survivor with the SOA but his power says otherwise unless you can get Ambre support on him perhaps).
try to get hold of Morphun or Ambre as well as they are the best leaders to have for survivor.
so with those changes the deck should look like this:
concerning shann: you may want to change her to Angie/Shogunn if you don't like her softened Pill manipulation however on most draws she will still get +3pillz (and still +4 if you draw Bangers + Morphun with her). The only issue with Shann is that you might get a little trigger happy with her so don't make any crazy moves with her.
