Rancor would do you some good, and build your champion up faster. Odric, Master Tactician would work in this deck too. Ajani, Caller of the Pride could also help turning a buffed up champion into a flying double striker.

Perhaps adding Selesnya Charm instead of Smite the Monstrous would be more effective due to the added versatility. It also gets around indestructibility.

yeah good idea ill throw some theyll be really helpful all around for this deck

Oblivion Ring. Illness in the Ranks and Legion Loyalist will mess your deck up something fierce.

I suggest Unflinching Courage and Silverblade Paladin . Either combo of these two with Champion of Lambholt destroys people's faces. I run something similar to this and have gotten pretty good results.

I would remove the Precinct Captain for the Silverblade Paladin btw.
