Charmed Shield isn't a Ward Save, it ignores the first hit on a 2+. I find the Arch Lector setup for my games an interesting one, at the moment with Warriors of Chaos coming out, Daemon Princes will be seen a lot and apart from Cannons there's nothing that can really answer a tooled up Prince.
Issue I have with the AL is spending nearly 250pts on a character, that unless it gets into a another Character doesn't seem to earn his points back. You have to protect him too, Opal Amulet is rubbish for me, I'd rather just take a constant 4+ Ward instead for an extra 30pts.
I'd run him with VHS, Heavy Armour, Barded Steed, The Other Tricksters Shard, Talisman of Preservation, Great Weapon, Charmed Shield/Shield/Enchanted Shield/Dragonhelm.
