Skeelz + Piranas (get rid of Andsom tho)

Ulu but Buck to Lulabee and Shanya to Hiko
Piranas but Andsom to Amber

You can also give a go to Montana (except for Sharon) with Nightmare.

Your pirana/Nightmare deck is ok personally i would remove Hawkins because it will allow you to draw your more powerfull cards more often. Also think about changing Hugo to Ambre/Morphun.

p.s if you want to make a link which is just your deck name you only copy the preset=1916267 and change the = to :

La Junta is not good for survivor, i personally think is the worst, because in higher survivor you have low pillz and La Junta doesn't help. You can't even use Emeth because you are playing biclan. And their dmg reductors are horrible.
Another thing: survivor without Sakrohm is not survivor

@maxiV La Junta is wonderful in survivor, Cards like Trish, Jane Ramba, and Bryan destroy the competition, and Survivor is not nothing without Sakroohm..... If you look hard enough, there is something in almost every staple surivor clan that can be used unstead to the Sakroohm trio. Vermyn N, Niva, Nistarok, Spiaghi, Jeena, etc., etc., and Soa clans destroy sakroohm, and Roots in T2 are a big powerhouse as well as GHEIST. So no, La Junta is not horrible for survivor, and no, Sakroohm is not the paragon in survivor

Ulu Watu and Piranas get rid of Andsom
