1500 point battle with inexperienced DE

Greetings fellow archons. I've collected DE since the day of their relaunch but since I only play 5-6 games a year and I prefer not to play with unpainted models I'm still a freshman when it comes to the dark kin.

I will be playing a game against a friend (a veteran 40k player) tomorrow, and he usually beats the daylight out of me. He will be bringing Tau or Sisters

This is my first 6. ed game so my list is a bit different than usually. Let me know what you think

HQ:

Archon with Husk, SF, ST, Phantasm 160 points

Elite:

4 Incubi 88 points

Troops:

2 * 10 kabalites, SC and blaster 230 points

2 * 5 wyches, HW, Hek, venom, phantasm 170 points

Fast Attack

6 Reavers, 2 CC, 2 HL 196 points

Heavy:

Razorwing, Diss, Flickerfield 155 points
Ravager, DL, NS 115 points


Dedicated transports:
2 * Raider, NS, Splinter Rack (the warriors go in here) 160 points
3 * Venom, NS, 2 SC (For wyches and Archon) 225 points


The idea is to rush a flank with to many targets for him to take them all out. The archon and incubi will search out his HQ and engage in CC. The wyches is on anti tank duty supportet by the ravager. The gunboats will wither down his infantri with some help from the Razorwing. The reavers will haras any small units (like heavy bolters for the sisters or the railsuits for the tau)

Ideas and critique welcome. Am I totally wrong here??


EDIT: Game over. Crushing defeat. He fielded more than 40 battle sisters, and I just couldn't cope with that amount of power armour.
The dice gods were not kind as well and many of the crusial rolls went to his advantage. Some of the examples of bad rolls I had include:
- Didn't get first turn (for the 5th game in a row), and no nightfighting
- Shadow field failing on the very first save
- Wtyches failing to charge 4'' even with the reroll
- His penitent engine being hit with 5 dark lances and only losses a single hull point.
- Archon needing a 2 to instant kill the canoness and gaining S 10. Rolls a 1!
