Magic Brawler

The team I used that went 10/12:

[npc=123650] (1/2/2) (You might be able to substitute Shadow for a Lantern/Wisp with Flash and Light)
[npc=88692] (1/2/2)
[npc=132366] (2/1/1)

Started with Shadow, using Flash then Light on cooldown, using Shadow Shock otherwise until Shadow Died.

Brought in Mailemental, used Return to Sender, then Express Delivery. If they used a pet with high health/recovery, I'd use Snail Mail on CD.

After that, it's Servant of Demidos. Use Soulrush on cooldown, same with Siphon Anima. Otherwise, use Magic Sword as filler.

I had trouble with every set I found online. Even triple wisps or lanterns are had to beat if the other person swaps them. Anyways, I ended up coming up with my own successful set and got it pretty fast.

I used

Enchanted Broom 2/1/2
Sapphire Cub 1/2/2
Blood Boil 1/2/1

With enchanted broom just keep the sand up, and for wind up, if you use it once and you know the other pet has some sort of block or flying up ability wait one turn. Other than that is pretty straight forward :)

I tried a few different teams, but the one that ended up winning the most was:

Anomalus 2/2/1
Enchanted Broom 2/1/2
Lost Quill 2/1/2

Open with Anomalus, Corrosion, Poison Protocol, Void Nova, Corruption till death or something comes off cooldown. Then Enchanted Broom - Sandstorm, then Wind Up until dead, then Lost Quill to clean up.
