Well, if you are throwing 18 dice a turn, your enemy probably only has two or three turns to survive. I do not think that you would need to worry much about dispeling enchantments, since they will be absorbing an average of 18 points of damage a turn from your paladin (plus whatever is coming from your entourage of creatures). By the time that you have two Knights of Westlock and two Guardian Angels (around turn six), you should be able to beat the stuffing out of your opponent's force.
Just out of curiosity, why don't you have a Battle Forge, the Dawnbreaker's Ring, the Signet of the Dawnbreaker, the Sword of Radiance, or the Veteran's Belt? The Battle Forge would allow you to get out your equipment more quickly while the rest of the stuff either improves your offensive or defensive capabilities. I would honestly consider replacing the Meditation Amulet with the Moonglow Amulet, for the sake of action economy, and I would suggest adding an additional Mana Crystal, so your channeling could reach 12 by the end of turn 2.
