Just for laughs, really:
Omega Red 124
Lambda-Zero 75
Shang-Chi 58
R Johnny Alpha 41
298 points. One of the BFCs will of course be Alpha Strike.

Too bad I do not have Lambda-Zero or R Johnny...

I don't think the Chi in Shang-Chi is the greek letter. Chee, not Kye.

Could be fun, though.

Put in Beta Ray Bill!

Don't forget to use the Alpha Flight alternative TA!
