I just purchased lord blackbolt yesterday thus completing my set of ihumans (until they finally release Karnak and Gorgon.

323 points

Black bolt
medusa
crystal
Lockjaw

I play in a 600pt. league.
we play with themes. the only thing they have for me is to play FF
Does anybody have some suggestions what to play them with, and what to do with them? (I'd also like to throw Namor in there as well)

Well those 4 by themselves (with a BUTTLOAD of feats) in a 600 point game won't fair very well... if you throw V Sub Mariner in and T-bolt Mystics, it will definately be more playable.

Quicksilver makes a nice addition as Crystals husband.

inhumans (as above)
with the addition of:
fantastic forces
Reed Richards
ben grim
exp. human torch

wht do ya think?
and the only feats they'll let me use are alternate team abilities
I was thinking of using the ff card.

Definitely use the Alternate FF card, and try to get ahold of a Veteran or an LE Invisible Woman from Fantastic Forces--she can then share her nice 18-19 Defense with the rest of your figures with the FF Team Ability.

Here is how the team could look:

U. Black bolt = 166
U. Crystal = 62
U. Medusa = 57
V. Lockjaw = 38

LE Ben Grimm = 123
E. Human Torch (FF) = 81
V. Invisible Woman = 67
BT Alicia Masters = 5
Feat Alternative Fantasitc Four Team Ability

Total = 599

Invisible Woman can then share her 18 Defense with everyone with the FF Team Ability, making you much more difficult to hit; and she can use her Barrier capabilities to further increase your defensive capabilities.

I would use Lockjaw to shield Black Bolt until he is in position to use his Running Shot to maximum potential--if you keep Lockjaw and Black Bolt adjacent to one another, Lockjaw can share Bolt's 17 Defense via Defend.

That way, everyone on your team has either a 17 or an 18 Defense.

Good luck...
