After thinking about it for a while, I used my monthly budget on the Coeurl Lurker lvl 2 (Taunt, Dodge, Phase) and the Scavo Technomancer lvl4 (Blast, Rust) - they're a great combination since the Lurker has high melee attack, and the Scavo lowers enemy's armor by 2.
Since them, I'm trying them out in different constellations. Here's my favorite outcome so far, very, very close. If it wasn't for Scattershot-Rule, it would probably have been easier for me.

As you can see, both teams are Silver level, which is quite cool since it's a fair fight.
I chose the Conquerer since I wanted the Piercing damage for the lurker, plus the 2 extra speed for it to evade more. The Scavo to reduce armor and a little exploding damage, and a Triage healer for the scattershots - and of course a martyr, in the back row hoping for a quick scattershot kill.
Even better for me and bad for my martyr's life, the enemy chose return fire as summoner ability - I was happy, the marksman was not. He also chose a self-healing tank with void armor, plus a repairer and reviver, and a ton of magic damage. Not a bad choice at all.
In the beginning, it looked like my lurker was still asleep, jumping into the first attack like a shield. Luckily, he evaded the melee atacks and gave the enemy tank a dent - which was healed and repaired right away, but a start. My marksman got hit, but healed - and I was fearing my Scavo was about to go out in second round.
He did not, but the Marksman did! Instead, the Scavo got the extra stats and healed by the Spirit hoarder. The enemy tank was now getting lower, but that slow lucker was able to place a hit on the Lurker.
Meanwhile, the explosions where already doing some damage in the back row.
In Round 3, the Spirit Hoarder got kicked out, and it was the damaged lurker and the Scavo against the rest, both with half their health but fast.
The Lurker almost got the the Knight, but even with the explosion from a hit on Adelade, he still had 2 health and healed himself plus his armor - but all the attacks missed the lurker. My team finished Round 4 as they started it, and it was getting very, very exciting.
In Round 5, the Scavo kills the Leech for the first time, but gets resurrected. The Djinn is the only one to land a strike on the lurker, leaving the tank open for a finishing attack.
The lurker finishes off the Knight, and the Scavo Adelade - but the Djinn manages to give the lurker the final blow, and it's only the Scavo with 2 life against a pending attack from the Leech - and the Leech misses! Given the health condition of the Djinn and the Leech, the Scavo strikes both down with attack and explosion in Round 7.
It was a really fun game for me to watch, and I was very happy with my Lurker's performance. It'll be on the field a lot more now, since it's a great defense against both melee and magic. But I'm still not a fan of scattershot.
Thanks again for reading! I hope you enjoyed it as much as I did :-) As always, I'm happy for any comments or remarks - I love to enhance my strategy :-)
