Argent Lance. Not a fan. We already have Coghammer. We need 3 damage on 2 mana. Not more 2 damage things, let alone a weapon almost identical to one we already have.
Doesn't even really make sense. The mechanic suggests it's for late game, high cost decks. But if that's the case, might as well just run Coghammer because who cares about the mana cost if you are a late game, control deck, and on top of that Coghammer has guaranteed 3 durability plus an additional Taunt/Divine Shield on a random minion.
I do not think it is bad. Paladin had no way to deal instant damage at turn 2 and it can kill a knife juggler immediately. I agree though, that the 3/1 would have been much better. It may or may not see play, but it gives something to paladin which it did not have before.
