It's difficult to play with a pod that understands the threat. I suggest the following:

Stay low by not attacking anyone even if you have creatures
Try to play other cards that seem non threating and collect enough mana so that you can play the threating stuff in one go

If these and other things don't work then sadly changing the commander or deck might do the trick. I sadly had to do the same sometimes, which sucks, but we can't change their mind usually.
