Just posting my "Brainsless" all around team.
All around because it has a great (not perfect) win rate in PVP, Explo, farm, etc... in fact, with Dragon soul and Skullbeard, you also rack decent money and souls.
Brainless because it's an exploder, so even if it's not as fast as other teams, you can basically just press spell and not think. Not even look for matches . Just press any explosions that are ready. Perfect for Netflix-binge playing.
The Dragon Soul
Siren (can be anything you like)
So basically, you have 3 cheap cost exploders with different mana. So, once it starts.... there is always one guy filled and ready to blow.
I use Siren last to kickstart it. You could bring anything really.
Order of casting is always TDS first, then Skullbeard, then Gorg.
