1500 yanari tourtment list

so my local game store is doing a tournament with one game played each week. the retrictions are the following....
no 20 power+ models
must take a battalion
1500 pts
must use the same army every week

meta includes orcs, chaos, space marines, nids, necrons, eldar, guard and a wild card.

this was what i came up with..
hq's

the Yncarne w/ ancestors grace and word of the phoenix

farseer skyrunner w/ guide and doom

troops
20x k-warriors w/ 2 DL
5x wyches w/ agoniser and hydra gaunlets (+1 attack)
5x wyches w/ agoniser and hydra gaunlets (+1 str)

elites
5x wrathgaurds w/ d-scythes

fast attack
6x windriders w/ shuriken cannons

transports
raider w/ dissy

Wave serpent w/  shuriken cannons and twin shuriken cannons

total comes to 1479 so i still have points to spend but not sure how to spend em? would love some help havent played many games at 1500 pts in 8th.

goal was the bikes ride with the farseer, wyches in the raider, and wraithguards in the serpant. soulburst the squad of 20 warriors when ever possible and or the bikes. let the Yncarne take out the big stuff.  would love to hear any suggestions.

also there are several custom made missions in eternal war style of play.

I'm very wary of the amount of AT you have, now I don't know the eldar codex that well or their units but it oooks to me that you have the large warrior squad and the raider with long range firepower and then the other at is coming from your d scythes, which have a very short area of danger (17" including movement, +3 if disembarking)

This makes target priority very easy for your enemy, and while you have 20 warriors in that squad, they are only warriors and it is going to get minced very quickly.
I assume the anti infantry shooting is good, a lot of shurken, cause I don't play eldAr. But it had better be cause your wyches and yncarne don't have much support up there in case the enemy counter charge, and wyches aren't exactly blenders...

what would you suggest? im not really sure what i could add to the list or change? i guess i am counting on doom for the AT. i do feel ya on it just dont have a ton of options. i had a list with a voidweaver but idk if that really fits the theme. own a ravager as well but no dark reapers witch i would love to add.
