I would take out lennox, as he is only a 6/6 with a good bonus and a nice ability, but he is not that good. I would prefer fixit, cause he has a very solid ability.
And ambre is fine, you just have to learn to bluff with her occasionally.
And how about putting in angie for chlora???
Sob is a very useful ability against montana for exaple. You don't have to bother about their -12 attack bonus.
I would change Lennox to Fixit.
