I am going to star a new army and I think that i might go with Dark elves. Mainly because no one else seems to want to play them any more at least at my GW. Now Im just trying to figure out what the dark elves have to offer. Im kind of tierd of painting hores of infantry and having next to no fire support such as archers and war machines. I was just wondering if anyone could give me some assistance on what a good start would be and how to make it tournament capable while keeping the model count low if possible.
Dark Elves are foremost a fragile, but deadly force, though their versatility can mitigate that somewhat. If you want to shy away from painting hordes, well, you don't have to field that many hordes with Dark Elves. Warriors and Repeater Crossbowmen are pretty much the only troops you're going to have a large bulk of to paint, recommended if you want to have a competitive list.
To keep the model count low, but effective, Dark Elves can make effective use of smaller units. Witch Elf suicide squads, Cold One Chariots with a character, Hydras, a decent sized Black-Guard unit, any of these can get good mileage with a relatively low model count. Certainly, you're going to want to get big units under the new edition, but smaller units can work well with Dark Elves.
To start making something tournament-based, start with a solid core. There are essentially 4 viable options for this. The first is a large Warriors unit. This is probably what you don't want to deal with, so I'll skip them. Second is Repeater Crossbowmen. These have gotten ridiculously good under the new rules. Either take small units of 10 or a large unit of 20-30. It is quite easy to fill your entire Core selection with these if you want.
Third and Fourth are the Black Ark Corsairs, or rather, the two different configurations for them. With Repeater Handbows, they make god, cheap screening units, just resilient enough to shooting to keep them from being worthwhile to kill, and just annoying enough to be a real problem for your enemies. There are also additional hand weapon Corsairs, often taken with the Sea Serpent Standard, who get a ridiculous number of attacks. Probably not as viable in a tourney though, in my opinion.
Considering these, Crossbowmen and RHB screens are the way to go with what you've stated as your preferences. Special units are a much more diverse group, with so many tactics and discussions about their worth that me putting them here would make this post even longer than it is. Pick what looks good, but be wary that Executioners are only really good in a large unit, and Cold One Knights have lost some effectiveness. Even then, all the specials are viable.
Now for Rare, Hydras, Hydras, Hydras. No brainer. For Lords and Heroes, Dark Elves can put out an obscene amount of magic, so one High Sorceress with the Sacrificial Dagger and a secondary Sorceress, perhaps with Death could fill a good amount of points. Always take a Cauldron.
Bit of a long read, but I hope it's some help.
