I originally posted all of this on Team Covenant, so will post links to those threads here.
Essentially, for months I heard people say that a swarm is an auto-loss vs a Phantom. I have never agreed with that statement, so i set out to find out ways to counter the high maneuverability of the the Phantom. The following are posts describing my strategies that I use to beat a Phantom with a swarm. It can be done, and often. At Worlds last year, i ran a swarm. My first 2 opponents ran a Phantom, specifically Whisper both times. The first game I won 100-31. I lost 2 ships total. The second game I won 100-0. Yes, i won against a Whisper list, at the World Championships, with a swarm, and didn't lose a single ship. It can be done people.
The trick is to think outside the "box."
The first article was my attempt at reducing the effectiveness of a Phantom by executing a maneuver I call the "Death Blossom."

The second article is what really laid the groundwork for beating Phantoms, the Drunken Shark opening.

The third article displayed some useful blocking techniques for getting into decloak areas.

The fourth and final article brings everything together, and lays out my overall game strategy for beating a phantom with a swarm.
You can disagree with me, that's fine, but I've beaten too many Phantom squads flown by too many different players to believe that a swarm can't beat a Phantom. And even in the games that I have lost vs Phantoms, I felt that I controlled the game and had chances to win. And before anyone says anything about my level of play, just remember the scene in "Hoosiers" when Gene Hackman had the boys measure the court in the arena. It was exactly the same as the gym back home. Likewise, my TIE Fighter dial is exactly the same as yours. The difference is how you fly it.
So take a look at my articles if you like. But please, stop with the swarm can't beat a Phantom hate, because it just isn't true.
