Here's a new army of mine. I need to gather people's opions of the army and any weaknesses u might think it has. I attempted to build a balanced force. Here it is.

total points=297
U Sauron
E Hercules
E Doombot
V Pyro
V A.I.M. Medic
E Blackcat
R Black Panther

Sauron carries Hercules, Doombot carries Pyro. Doombot moves for free and adds one to Pyro's attack. Blackcat can also move for free. So LMK what u think.

Not bad at all. Like you said the carrying for free will be key. Couple things. Go to V Doombot. The leadership and added move are well worth the 5 extra points. You can get these by either downgrading your medic or going to another kind of medic (AIM guys are expensive). Otherwise, looks good!
And if you want some advice, I would have Sauron carrying Pyro. This way it won't be a good idea to base him. Herc can take care of himself.

I would definately stick with the Herc/Sauron team up. That way, you can charge with Sauron's blade, and then pound them with Herc. Between the 2 of them, you should be able to either completely KO or at least cripple most of the pieces in the game. Sauron is also push friendly, thanks his Steal Energy, so on the second turn, you should be able to finish what you started. Pyro is a ranged attacker, and leaving a 75pt attacker with him as a bodyguard is a waste of resources.

The only change I'd recommend depends on a couple of factors - what's Pyro's purpose? Is he mostly there for Barrier? RCE? Energy Explosion? Or all of the above? If he's mostly a barrier piece, downgrade him to a Rookie, and upgrade your other pieces. If he's an RCE piece, a Rookie Invisible Girl will work wonders on your team. If he's an Energy Exploder, Psylocke is a must to enhance his damage. I'd probably drop Black Cat rather than Panther.

one words advice is good sauron will be a support fig for pyro while he is blasting away (Frying his Opponents) so when someone bases pyro charge with sauron and damage that insolent fig hehehehe

but mainly the team is well balanced i suggest you change black cat to a rookie Destiny she can be a much cheaper fig with PC. and you can use now the additional points you have with some other support figs.

So from the advice given I've now gotten this.

U Sauron
V Pyro
R Destiny
V Paramedic
R Black Panther
V Hercules
V Doombot
total 299

I'm still not sure who should carry who, but I'm leaning towards Sauron carrying Pyro, Doombot carrying Herc. Does this sound better?

Deadpool has a point about the big hurt Sauron and Herc can put on someone, but I wouldn't put all my eggs in one basket. Otherwise you could be busy slashing away at someone and they could just send someone over to base Pyro/Doombot and do the same to you. Against a team with only 1 Threat (Ultron Teams/etc) You may want to go with Deadpool's idea however. Under typical circumstances, I would fly herc with the bot and Pyro with Sauron. This way, Sauron and pyro can serve as a Super Cavalry to wherver on the board it's needed.
