My suggested teams:

Team 1: Stoneskin Lightning Cage (all four)

Kimi (faster than the other three) + Ukko (600+ acc) + Venus (600+ acc) + Cupid (pure damage)

Team 2: Bolster + Brogni

Mithrala + Brogni + Duchess + Leo

Team 3: UDK Shenanigans

Pythion (700+ RES, 250+ SPD) + UDK (tanky AF and slow as a rock - I used Guardian set on him too) + Nekhret + Rotos

Thanks for the suggestion. I will need to work on some accuracy, pulling 600+ with decent stats alongside are rough. I have some sets with those numbers thanks to iron twins.

For shits and giggles I tried out the dutchess, Mithrala, brongi, and Leo in reg arena(I know not the best metric as 3v3 is a completely different beast) against some pretty strong teams. It works very good just long damn fights lol. 

The accuracy numbers for team 1 are purely for arena defense, because you need to be able to handle Mithrala teams that run much higher RES than normal. On offense, you can afford to be closer to around 350-400 ACC if you want to avoid fighting Mithrala with that team.

As for the length of fights - sadly no way out of that with these go2 teams.

Also note that for team 1 it is quite essential that they *all* have both stoneskin *and* lightning cage. Without both, it's just too much of a coin toss to avoid buffs being removed.

Also, I forgot to mention in team 2, Duchess should likely be in Shield + Brogni in Bolster (or vice-versa). I have Mithrala in Guardian.

Uhhh... You resting Rotos,Nekhret and Mithrala ? Pure waste. Those three is top in Go2nd teams. Use them. With these legos easy to reach Gold1

Are you responding to me? Pretty sure all three of those are in my suggested teams.

Pretty sure he is coming at me there.

I've used nekhert and Mithrala in team comps before. Yes I've slept on building rotos as I haven't needed him yet.

My OP has my current teams I've been running for a few weeks now. I have not focused a ton on 3v3 as it is imo one of the absolute last areas of the game to push into.

Like I stated I'm coming towards the end of romantu quest line and it's time to get the effort into 3v3.

Sorry I'm not the perfect player.
