4 characters that can deal damage, and the mid game has a lot more of friendly characters... Electro should be hidden, and GG + Headpool should put tokens. Skadi helps with the big guys that could hurt the goblin.

I would be having Skadi's Warbot TK throwing Headpool with that build. It helps Electro save some actions.

The main purpose for headpool is put The first token to allow the Electro's SP, but with Skadi that doesn't work

Great team, just played a tournament (3 rounds), and each game was interesting...
Skadi still is awesome, best filler that I could ask (and don't break theme)
Headpool, just help a little bit less, he is good and a great harasser... no complaints.
Electro is my favorite zombie.
GG is my only worry, maybe Rhino could do a best job but with GG I just kill a lot of pieces, great damage output, but keep him safe was complicated, anyway when the enemy was looking to electro, he was able to eliminate the remaining forces
That ATA is mandatory for this team!.

I ended 3-0, and won a Sentinel Alpha 3, so It was a great local tournament.
