I'm rank 15 in constructed, almost exclusively playing as paladin. If you are trying to say it's not viable to reach rank 1, that might be true, but it's done okay so far.
Paladin is actually really good vs the very common hunters. The key to beating hunters is to keep your minion count low, so they can't vulture + UTH for insane card draw. I usually limit to 2 or 3 minions at most, unless I know he has already played 2 copies of UTH or vulture.
Anyway, why is paladin good? Weapons. Truesilver champion is a great way to get some board presence vs a hunter without feeding UTH with a higher minion count. Sword of justice is great for making your hero power guys a real threat. Consecration & avenging wrath will often wipe out the entire hunter side, and do some damage to the face as an added bonus.
Yes I meant to say to move up in ladder, Paladin sucks. I might have seen 1 after hitting 5 and just facerolled him. No offense but the hunters you are playing against either just suck or don't have the right cards like leeroy jenkins or traps.
