I've been playing Magic on and off for a number of years now. I got back into it right before M12 came out. I like playing standard because I like the pay-as-you-go approach, as opposed to dropping hundreds of dollars at once on a legacy deck. It also forces me to keep making and playing new decks, which is half the fun.
I did recently drop my collection to pick up a legacy deck, and I've been having lots of fun with it. The people at my LGS help me tweak it, and it's been smooth sailing.
I also love playing in limited formats and EDH, because they turn deck making into a skill, and forces creative play choices.

Following that logic, it is often hard to justify having too many one-ofs. Having a silver bullet or a situational card in your deck isn't always terrible, but having too many of them will almost always lead to problems.
Pick one thing you want your deck to do, and make sure it does it well. It's important to understand that no deck can be good at/against everything at once.
When building a deck, you ALWAYS need to be able to justify why you chose to put (X) copies of each card into your deck. You don't always need to be right, but you always need to have a defend-able reason.
"Why are you only running 2 copies of Sarkhan, the Dragonspeaker ?"
"Because he's bad in multiples, and I don't want him clogging up my hand at 5 mana."
"Why are you running 4 copies of Polukranos, World Eater ?"
"Because, even though he's legendary, I want to see him every game. It doesn't matter if he clogs up my hand because if they can't deal with the first one I win."
Seems like a nice way to level the playing field against noobs, but only against noobs that don't have access to decent cards yet.
A lot of new players will pick up a netdeck and just play it as they learn the game, and those noobs will probably mop the floor with anyone playing Handicap. Sometimes deck strength truly trumps player strength (after the initial learning curve, anyways).
The CMC of a card is always based on the cost explicitly printed on the card. Because the printed cost of Maelstrom Wanderer is 5RUG, his CMC is 8.
Commander tax, alternate costs, additional costs, or effects that reduce costs will never affect a card's CMC.
The problem for aggro in Modern is that, at their heart, all Modern decks have to be "fair" decks or they get banned. Because almost all decks rely in some way on creatures and board presence, as opposed to relying on Show and Tell or Goblin Charbelcher , the most efficient disruption to put in your maindeck in most cases is going to be creature removal. When every deck in the format runs 4-8 one or two-mana kill spells, aggro becomes a bad option.
