I need help building a 300 point team all marvel.
This is what I have so far
U stilt man
U scarlet spider
Will you fellow realmers help me out?
I need to complete this team by the 9th.
Thanks and please help me out!

It's tough to build a team when I don't know what you have, so I'll only use Sinister figures/Feats to keep this simple.

Here is one idea for a team using Stilt Man and Scarlet Spider:

U. Scarlet Spider = 86
V. Valkyrie = 71
U. Stilt Man = 57
U. Ka-Zar = 40
E. SHIELD Sniper = 22
E. HYDRA Technician = 19

Total = 295

This leaves you with 5 points to play around with: You could add BT Mary Jane Watson-Parker; Knockdown is a possibility; Vault could also be employed.

The idea is that you have Valkyrie share her 18 Defense with Scarlet Spider at all times, serving as a bodyguard while he attacks; SHIELD Sniper and HYDRA Tech should also be next to Scarlet Spidey to lend a hand.

Ka-Zar should act as a tie-up piece/pit-crew buster; Stilt Man should Charge and run interference with his 2 Square adjacency when he can.

It would be helpful to know what sort of collection you have.

Good luck...
