The more you goldfish the deck the more familiar you become with what hands to keep and what not to keep. After a while, you start seeing cards as fixer, one mana gain, two mana gain, LED as post wish or belcher mana, etc etc. After you know all the possible combinations, you can decide whether or not you should mulligan with only a quick glance at what your opening hand is.
For Nihil's second suggestion, that's something you're going to have to work on over time. Knowing your matchups (especially game 2) is extremely crucial. First game you will goldfish more than half the time based on the fact that most decks aren't well equipped (besides blue-based ones) to counter a turn 1 belcher activation or even 10+ EtW tokens. When you head into game 2, all sorts of hate comes in, and that's when you'll have to judge whether or not your hand is A) resilient enough to fight past hate B) has enough disruption to push your combo through C) not good enough and in need of a mulligan.
If you're not for ballsy decks, I don't think you should play this. It really is hit and miss, and if you play against blue-based control and hate cards all day you're probably not going to do as well. However, it is fast and consistent which, on the other hand, makes your opponent mulligan and play according to your rules. The fear of dying on the first turn alone makes this deck a menacing threat.
Oh yea, a lot of people seem to be misunderstanding Street Wraith's function. You're asking if mana should replace him? Well then, what kind of mana are you talking about? All the best red mana production spell are already in this deck (one's that net you +1 or +2 red) and by running Street Wraith you are effectively cutting down your deck to 56 cards and increasing the chances that you'll draw the good mana production spells.
