Well, with the new Doc Strange, it gets much more interestign doing Defenders theme teams!

V Doctor Strange 110 w/Force Field 10
E Beast 59
V Hellcat 38 w/Pounce 15
E Iceman 36
E Black Cat 32
300 exactly.

Or, if you go mor for thematics than for TA sharing, you could use the following:
E Dr Strange 96
U Moondragon 71
E Beast 59
V Hellcat 38
E Iceman 36
Unfortunately, no room for feats here. On the other hand, it adds TK... And Moondragon is one of my favorite figs...

Moondragon's great... despite the fact that she was cruelly snubbed by not receiving any TA(I mean, this is a character that spent a good amount of time on both the Defenders and Avengers team, as well as teaming up with Adam W. et al during the Infinity Gauntlet tales... if anything, she should've been a wildcard!).

Nice teams... I prefer the latter, of course (as if you couldn't tell ).

Nice team but since most tourneys are top heavy with big figures I would suggest a slightly different Defenders team to make yours more competitive.

(V) Dr. Strange 110
(E) Black Cat 32
(E) Iceman 36
(LE) Ant-man 43 + T'bolts
(U) Moondragon 71

with this team everyone now has a 20 Defense and Doc. has a 22 against ranged attacks!! Moondragon has tk which could become very useful plus she's not a bad dmg piece. Just keep in mind without Doc. you will fold like a bad texas holdem player. You might want to replace Moondragon with close a combat guy such as beast but or Hellcat.
