Two reasons:

1. I've come to believe that a Rogue deck that runs Conceal is more suited for a Double Auctioneer list because Conceal simply makes auctioneer more powerful.  Usually the 2nd Auctioneer is more of a minion than a draw mechanic.

2. Some times you'd rather not waste spells drawing with Auctioneer because some spells must be used with Malygos.  So instead you use Sprint to possibly save the use of four spells and just draw four cards.

I disagree for two reasons:

I've had trouble with hunters recently too.  You see we have to mulligan for early game, but get lucky enough to draw into a good mid-range curve.  Also sometimes it is not best to gadg + conceal because of deadly shot, so dropping a minion to bait it out must be done.  AND Sap has to be saved for a Highmane in most cases or it just fucks us.  And lastly we must also be wary of how many minions we play because of Unleash the Hounds.  With all these things in mind I still have a positive win rate over them, but not by much.  I've taken out Xaril and put it Harrison instead and that helped quite a bit so you can do that for now.  

Against aggro or fast decks that you're having trouble with, the usual right play is to remove their board as much as possible.  If you've gotta use prep+spell early game to remove something then just fucking do it.  The secondary way to win is to race them to lethal.  

Against defensive decks that you're also having trouble with, you have to always have in mind how much damage you have in your hand and in your deck.  Get a Decktracker for this, just google it, it'll help tons.  Once you are aware of your damage then your plays will follow suit.  Also don't flood the board too much or you will get punished by AoE.

Take out Xaril and put in Harrison Jones.

Last thing.  YOU ARE GOING TO LOSE A LOT OF GAMES LEARNING THIS DECK.  I must have went 10-100 Win/Loss ratio when I first picked up Miracle Rogue.  It's difficult to play.  Very difficult.  But once you do get the jist of how to win consistently with the deck, then it will be awesomely satisfying.

That's a very broad question my man and you're going to have to be more specific.  The mulligans are correct but this deck is definitely about the plays you make rather than the cards in your hand; and that comes simply with experience.  

As far as T2 dagger, if I simply don't have a T3 play, I'm going to hit.  Later in the game, I'm either going to hit if I know I'm going to dagger up next turn, or if I'm setting up lethal.

2nd Farseer, Shiv, Questing Adventurer (However this card is LEVELS below VanCleef, but it's the closest replacement)

I think the card is definitely not bad for sure.  However it is absolutely useless against slow decks, like you're spending 5 mana for a 4/4 in those match ups.  Ladder is always wacky where you get 10 aggro matches in a row, then 10 control matches in a row.  So you really have to find the middle ground when teching in cards like Cult Apothecary.  For example I tried Dark Iron Skulker because of Shaman/Zoo/Hunter matchups I was getting.  It was awesome for those matchups yes, but it was absolute shit in the control matchups.

Any one of those decks is very strong and can achieve Legend/High Legend ranks if the time were put in.  It really depends on personal preference so I'll bounce this question right back at you:  What do YOU want to play ?

I am aware if the southsea faceless combo.  The biggest reason why I don't like it is because it cost two cards.  Taking out a fan means you would get demolished by aggro/fast decks even harder, which is one of our hardest match ups.  I don't like it.

1. Edwin VanCleef

2. Bloodmage Thalnos

3. Leeroy Jenkins

4. Xaril, Poisoned Mind

You can make a couple changes to the deck like remove Leeroy and second conceal for another farseer and a shiv or something.  But I've tried doing multiple changes like this and always go back to the leeroy and second conceal just because there are so goddamn good.  To be honest just mulligan as best you can and sometimes you just have to ignore their minions and race them down.  With 2x cold blood, 2x eviscerate, and leeroy, it's definitely possible.

Couldn't have said it better myself.  SeemsGood

Depends really.  If you are an avid Rogue Player who doesn't only play Miracle Rogue, then Xaril can be considered more important.  However if you just want to play Miracle Rogue then Leeroy definitely takes priority because he is useful in other decks in Hearthstone as well.

Edwin.

Nice!  I've actually been thinking to make that change as well whenever I just run into 10 aggro / fast minion decks in a row.  SeemsGood
