So, after giving me all the dupes it could find in the latest eggs, the game accidently gave me a soulstealer in the last hatch 
Because of that i’m now thinking of the best possible way to use him in a frontline without having frostrider, since i didnt care for online events when you could get him in one dungeon challenge in the past (yeah, i know, stupid me ) I’ve seen some different setups including soulstealer, but i was wondering which might be the best alternative solution. 
Not sure if this would work, but I came up with something funky:
Gear croc
SS
Archwolf/Anubirom/Seahowl
Parasardon/Remus
Blitz
Sleepbomb
Stun entrance healer/purifier
Preferably Leg TT
Sweepers and other stuff
…
Shocking entrance
Hopefully you can knockback first, but either way something will get stunned hard whether you get to switch back into shockin entrance before or after Remus/Para dies. Then just send back or stepback as needed into sleep bomb? They should die before TU wears off, and you can purify the sleep bomb if times well for SS to continue the carnage.
Might be using too much space to set up SS though, but I tried to make it more fool proof (except there’s Robinator)
This idea is completly new to me, but it somehow sounds good But you already pointed out its weakness which would be the relatively high amount of needed space 
try Soulstealer, viridizardon, any super epic protector, and any one on one throw monster, like shadowbaron or luxking.
post a pic of your mons. that’ll help
Honestly you could just use soulstealer and any protectors you have in the front line. All you need to do is stall until death sentence goes off, and if you can’t do it by sleeping them then just have a bunch of 4/5 star protectors in front of him
So basically Soulstealer, auto Protector, protector, and a one on one guy? Wouldnt it be better to use an epic one on one? Theyre faster and have hold ground, so a twin killer would need at least two shots.
With death chicken around…getting soulstealer off aren’t so easy no more…especially if death chicken pair with sleep/protector killer…
Only combo who could be dangerous would be death chicken and kami/shadowyrm, which i’ve never seen in pve and very rarely in pvp. In all other case the auto protect will die and soulstealer will survive with hold ground. Bringing in blitzdragon into stunning entrance/heal all into blitz wont give the twin killer a second chance to attack.
As a player that has mainly used SS frontlines without Frostrider, I’ll put my two cents.
The one on one epics are the best to do that but they hang around without packing too much of a punch after DS has gone off. They are safer to use instead of the SE mons though. The SE mons are slower but can make kills on their own. Your choice.
If you have problems with Robinator (you will) put in Viridizardon for the auto protector. Works great after the game stalls out with that Survivor. Megabombs are also a decent choice, but I haven’t tried them. Nightrider also works surprisingly well if you have him and Bazilogon and Warca are also great allies of SS.
However, Shadowyrm and Kamiwyrm are complete counters, very fast and stun immune, those two will wreck your frontline. I haven’t figured out a way to deal with them safely yet and I don’t think there is.
Thanks a lot 
Will try to use it with viri or maybe taloknight can get the job done too. Well, in pve, the twin killers tend to attack the protector first, so with either kami or shadowyrm its possible to deal with, if youre able to sleep them after their first attack with 1on1.
The epic one on ones have hold ground aswell the super epics don’t so I would chose a epic
Oops ;), the only thing with the super epics and why they are that much better is because they have throw, along with bloodcrave.
What you SHOULD do is have an epic starter that is a protector but also has purify, have soulstealer, and luxking for an all out blowout. You only need 3(I believe) to trigger soulstealers bloodthirst, so that would mean that you can kill one of the 4 with luxking, and keep killing and killing until, 1, everyone wakes up, or 2, death sentence all kicks in. After that you have a pretty good homestretch.
Soulstealer was my first legend, and this was my way of coping with it. I also used other sleep characters like Lunaverios and magmaliathon to help soulstealer, as well as having a carnofrost and use the ability, unwanted friend, to help trigger that bloodthirst for soulstealer and the other two
Only need 2 kills to trigger bloodthirst.
Using a super epic one on one makes weaker to twin killers on the other side since they are a lot slower than their epic cousins
