A mono deck is hard to pull no matter what clan you're using. But yeah i think you can make a good one using Jungo.
Good,balanced deck with several cards capable of turning the game to your favor...
Jalil / Odile / Dagouba
I think Jungo's been viable for a few releases now -- although the regular bans on Sylth hurts it's ELO ability a bit.
Nyema is definately a welcome addition to the ranks. Potential for an 8 point life gap (3 Damage, +5 Life) that jumps up to 12 with Fury (5 Damage, 7 Life)? What's not to like, especially in a 3 star card? Team her up with Scopica and you'll nearly double your Life while halving the opponent's.
Adler...well, Adler's basically just a leveled up version of Scotty. An 8/6 Stop: +3 Damage rather than a 7/5 Stop:+3 Damage.
Personally, for a 5-star I prefer Askai's 7/7 -12 Attack, since it doesn't depend on facing a SOA card.
Somehow my previous post was cut in half.
Here is the rest:
Jalil / Odile / Dagouba this is where it fails, just use a Uranus in that spot
...or a more risky one.
Askai / Adler
Elea / Borss it fails here now, i would use Spiaghi
You can also go 54433222 with Niva but you'll have the same problem with the level 2 cards.
Ongh, Radek and Mindy are terrible.
Good Jungo characters:
Niva: a 4* Hattori
Jalil: a 3* Crassus
Nyema- I find her playable BUT to be honest she basically compares to Anita, who is much better but still mediorcre
Pegh: The only 2* Jungo worth using, is better than Gabrielle
Boomha: a 3* Rowdy. You should play him in Mono Jungo
That leaves you with 7* for
Askai or Leader + Bors or Mindy
Slyth or Greow + Odile
BUT you still have NO SOA, only Bors for SOB, rather limited damage reduction etc...
Your characters pack a lot of punch at discount, but they can't provide the best abilities.
For the SoA I was thinking swapping out Ongh for Psylo and putting in another 3 star, since the Jungo 2 star is weak. So to take WarPigs deck as an example, it would become:
Askai (C) / Adler (C)
No idea how that would work...might be worth a shot.
