Marines are well known for they're ability the swarm the battlefield, sending in wave after wave of heavily armoured warriors in a seemingly unstoppable tide of stoicism and insufferable smugness in their belief in the false emperor.
There's one big caveat: this list is built with a team-style event in mind, where each army/codex can be be used once in the team lineup.
This means the Space Marine slot is likely to be taken up with bikes or a strike force, so Dark Angels is the next best thing to do this.
The army plays as an aggressive attrition list. Expect to take heavy casualties. Lots of casualties. You are not going to win any kill point games. The point is that all the objectives are taken at the end of the game, no matter how many fallen marines litter the battlefield. Besides, they're marines, there's no shortage of marines.

The two Battle Companies allow units to purchase free transports, hence the MSU spam.
Those with a keen eye will have spotted that there are 15 Drop pods, and a total of 32 Objective Secured units. Having to clear all that off the table will eventually drive your opponent to boredom through exasperation, thus assuring you victory.
There's a healthy dose of melta, plasma, and flamer. The usefulness of traditional special weapons in the age of grav and destroyer superweapons is questionable, and there's no fancy twin-link or ignore cover tricks.
Main weaknesses are horde armies, as there isn't quite enough bolter shots toe hold them back, and flyer armies. But everyone known flyers are bullshit so we're just going to ignore them.
A few alterations for local tastes are possible.
The devastators have been repurposed as bolter marines. They could be given a few heavy weapons and deployed normally instead of dropping in.
All the drop pods can be replaced by razorbacks, offering a large number of twin heavy bolters. The advantage of the drop pods is the alpha strike potential, and board denial if some jerk turns up with Tau or
