You don't need to have Excalibur as your Warframe to join :D

Guys unfortunetly we are already too many players to all play in one clan war game so....if someone wouldn,t like to join a clan war game pls speak now you will not be humiliated or anything I can assure you but we need the right ammount of players to join a clan war game. TKS
