Assuming you are talking about my list (post #2073) you could not be more wrong, it is more of a control pure control deck than even Miracles. By your classification of a deck as combo for containing 1 or more card that can combo finish a Miracles list running 2 Entreat the Angels is 2x the combo deck as the Loam Pox lists posted(Mr. Safety also ran 1 Dark Depths post #2072) The ability to Combo kill out of a control deck is just good deck building.
What you call bad luck, I call bad deck building. If you play a deck like mono black Pox and expect to perform well late game without some sort of library manipulation good luck against a deck with Dig Through Time or Brainstorm. And saying you didn't do well with Sensei's Top when you didn't run fetch lands is again bad deck building, why would you not run shuffle effects with Sensei's Top, take your own advice and make smarter card choices. Pox plan is to answer all their threats and get into a top deck game as soon as possible, mono black gets to that point then has to hope to top deck better than their opponent. I would never considering running a mono black pox list without sensei's top and fetch lands. G/B playing things like Sensei's Divining Top, Sylvan Library, Crop Rotation, Life from the Loam to allow us maintain control into the late game.
If it sounds like I am attacking mono black players I am sorry, I just get pissed off when uninformed people make rash judgments about things they know nothing about (Applies to everything in life not just Magic decks). I love a Smallpox deck in any incarnation and will support anyone who plays it or any other deck in Legacy. I also love Legacy and will support anyone looking to play the format. I will also gladly give my honest opinion of any deck choices for pox or any other deck. I am fully supportive of playing suboptimal cards for any reason as long as you are honest with yourself about why you are playing them (budget, pet card, fun of, are all valid reasons to me but don't say it is better when it is not, cards like Sensei's Divining Top and Cabal Therapy are 2 examples of cards that are difficult to play. not feeling comfortable enough to play them is one thing saying they are bad cards would be wrong)

P.S. I have never lost to Mono Black Pox ever, including late rounds of big events like Legacy Champs.
