I have played a red defense with Babs before, here are my suggestions.
Take out
Adino, He is not as powerful in game play as you might think, even with his spear.
Army of Simenonites, He is strong but clogs the way for the other better cards.
Men of Judah, same reason.
Foreign sword, same reason as Adino.
Most of the red enhancements, Take out the 6 worst ones in your deck for the cards below.
Put in
Uriah the Hittite, very useful with many different GE's.
Ishmaiah the Gibeonite, for banding and drawing.
The centurion at Capernaum, good if you have nothing else to attack with.
David' Triumph, necessary.
Centurion's proclamation, also necessary.
David's mighty men, you would be surprised how many times you get to use this.
The battle is the lords, One of the best negates in the game.
Bravery of David, absolutely necessary!!!
Freedom! It is fun removing your opponent's cards with no cost.
Rams horn, Best with Freedom!
This will make your red deck much better.
God Bless!
