I remember a long time ago that there was a rule about how many points can go into feat cards. Does this apply to resources as well?

While on the subject, am I allowed to build a team with all three components? A resource, a feat card, and a battlefield condition? I've been tinkering with a 500 point "anything goes" team consisting of:

Batman/Superman Robot - 300 pts
Robin - 72 pts
Batgirl - 42 pts
Toymaster - 30 pts
Green Battery and Ring - 10 pts
Nurse, Catapult, Crossbow, and Shield Constructs - 38 pts
Camouflage Feat Card - 8pts
Deep Shadows BFC

What I am wondering is that my first team did not have Deep Shadows. Originally, I had the Net construct to give that robot stealth wherever it went but then I realized BFC's were allowed. Is this worth the switch? If legal, of course...

No. There is no point restriction to a resource. However you can only have one resource on your team. And when you play a resource you may not play special objects unless they are brought in through the resource or from outside the game. Or something states that the special object does not count against your force.

The rule for feats is that you may not spend more than 10% of the build total on Feats.

As long as the game doesn't require the force to be modern age legal, or in any other way restricts feats, BFCs or resources then sure.

10% Cap is on Feats only.

Remember Feats and BFCs are Golden Age. And that any BFC could only be played in one round of a tournament.

Good point as I did not know this. I think I will revert back to the original idea in having the net as I don't think I can change my build between rounds.
