Below is the list of interesting cards with the lady, from Standard only. It also includes some cards which become exceptionally good, but people don't think about them because they are not played right now and are not memey enough to be remembered.
Northshire Cleric and Dire Mole - 1 mana 3/3
Shieldbearer - 1 mana 4/4 taunt
Wax Elemental - 1 mana 2/2 taunt divine shield
Lightwell - 2 mana 5/5 that heals 3 at the start of turn
Doomsayer - becomes a 7/7 so even if opponent trades into it his minions still die most of the time
Lorewalker Cho - 2 mana 4/4 and can be an interesting inclusion in Spiteful Priest
Nat Pagle - 2 mana 4/4 that draws you cards sometimes
Devilsaur Egg - 3 mana 3/3 that summons 5/5 as a deathrattle
Drakkari Enchanter - 3 mana 5/5 that doubles your end of turn effects (if there is anything you want to double)
Imp Master - 3 mana 5/4 that summons 1/1s and can be healed up
Injured Blademaster - 3 mana 7/3 that can be healed up
Lone Champion - 3 mana 4/4 divine shield taunt and a good card to play early in the game (before you played Lady and because your 2 drops might suck without Lady)
Mindbreaker - 3 mana 5/5 disable hero powers
Stonehill Defender - 3 mana 4/4 taunt Discover a taunt
Tar Creeper - 3 mana 5/5 taunt (7/5 on your opponents turn)
Tortollan Shellraiser - 4 mana 6/6 taunt that gives +1/+1 as a deathrattle
Hozen Healer - 4 mana 6/6 that health one of you high health minions to full (and you probably have many of those)
Kobold Monk - 4 mana 6/6 you hero cannot be targetted by spells or hero powers
Mogu'shan Warden - 4 mana 7/7 taunt PogChamp
Oasis Snapjaw - another 4 mana 7/7
Stormwind Knight - 4 mana 5/5 charge (who even needs 5 mana 4/4 Rush?)
Gurubashi Berserker - 5 mana 7/7 that gets +3 attack whenever it takes damage
Hungry Ettin - 6 mana 10/10, which summons a 2 drop for your opponent (and even if it is a doomsayer, you probably have a 7/7 to remove it)
Skulking Geist - 6 mana 6/6 and is not a serious tempo loss anymore.
Corridor Creeper - 7 mana... erm... I mean 0 mana 5/5 (UNNERFED!)
Stormwatcher - 7 mana 8/8 windfury PogChamp
Grand Archivist - 8 mana 7/7 which casts Free From Amber or Mind Control
Primordial Drake - 8 mana 8/8 taunt with 2 damage AOE
Obsidian Statue - 9 mana 8/8 taunt lifesteal with a deadly deathrattle
Ysera, Malygos, Sleepy Dragon - 9 mana 12/12 seems good.
Ultrasaur - 10 mana 14/14. He is huge!
In addition you can include Crazed Alchemist and Void Ripper as a back up plan for when you don't draw Lady early enough. And have enough dragons to do the dragon synergy thingy with Duskbreaker and whatnot.

My stats are:
Rank 15 (was 13 before start playing this deck)
22 game lost
8 won
If this is not a troll deck (which I am not sure about), it has some major problems. The main problem is that is absolutely useless against aggro, the second is that is unplayable against jade. These categories represent the 99% of decks at rank 15.
My opinion is that if you're under level 10, don't play this deck.
