ELDAR what should i have

[oldone]

Lucky you, Fire Dragons are great

Eldar work best as the fluff describes, a highly mobile and specialized force.

Generally, you'll want something like this.
Farseer (buffs and debuffs, provides psychic defense)
Fire Dragons in Serpents or Falcons (best tank busters in the Codex)
Dire Avengers in Serpents (mobile and blasty scoring units)
Fire Prisms/Falcons (cheap and speedy battle tanks)

From those building blocks, you can assemble a solid army. Keep everything mounted, keep it mobile, and know what you need to do with each unit and take them out.

How small we talking here? Points level somewhat impacts the way you should build your list.

I'd start accumulating Wave Serpents. Don't stop. Don't ever stop.

I've done pretty well with the following

farseer
2 x 10 dire avengers in serpents with scatter lasers
1-2 units of scorpions
Wraithlord
10 wraithguard

other variable units after that.

avengers zoom around and blade storm targets before zooming off again

wraithlord is a long range fire support unit

Scorpions usually come on flank, if the dice are with me, and the wraith guard with a warlock take all the attention.

You want two units of fire dragons for dual threat. They are a kind of throw away unit, but they will get the job done
