DE OOMIES!!!

WAAAAAAAAAAAAAAGHHH!!!!!!!
Okay, now that I've cleared that out of my system, I'd like to start off by saying I'm a first time poster here and that this site looks really cool.
Anyways, I'm going to just get straight to the point.
I want to make a list that will include a bunch of fun items in it that games for me wouldn't be complete without, but at the same time to still be able to defeat my main rival (my brother).
For those who are interested, he plays Dark Eldar and runs a very competitive list. Some of the main weapons in the list include an Archon with a 2+
inv save with a squad of invincible incubi in a venom pretty much with all poison attacks. The rest of his list basically is composed of witches/other troops in venoms which out dakka my orks completely while remaining mobile. He also managed to fit in a couple reavers and a few other units, but basically his army is SUPER

ing powerful.
Alright, now with that in mind, here is the list I've made:
HQ
Wazdakka - 180pts
Elites
3 Nob Bikers w/
PKs + Eavy Armour - 110pts
15 Lootas - 225pts
Troops
10 Grotz w/ runtherd - 40pts
20 Ork Boyz w/
BS, RL, and Nob w/
PK, Bosspole - 175pts
3 Warbikers - 75pts
Fast Attack
3 Deffkoptas w/ twin-linked rokkit launchas + 1 bigbomb - 150pts
Heavy Support
Battlewagon w/ deff rolla,
RPJ, Grot riggers, armour plates, kannon, 3x
BS - 155pts
Looted Wagon w/ boomgun,
BS, ard case,
RPJ, Grot riggers - 130pts
Total: 1240pts
I stopped at 1240 because I'm not sure what to add on to the list.
Currently, my horde seems a bit small so maybe another mob of 20-boyz sounds good.
Then, since he says his transports are open-topped, I was thinking either another unit of lootas or a unit of burna boyz. The flames would go into his poonee little elduhr shipz and burn the poonee little elduhr.
I was also perhaps thinking of adding in a Big Mek w/ custom force field to accompany a unit of boyz who may or may not have enough of a budget to get a transport so that they get some protection from incoming fire.
However, overall my bro's list counters everything I have going for me. He counters my mobility by being Dark Eldar. He counters a potential horde by having hundreds of shots per turn. He counters lots of wounds or heavy armour by having poison EVERYTHING. And he counters vehicles by having dark lances on his.
What can I do? What's the best bet of beating him? And, if there truly is no hope for me, what is the most stupidly insane way for me to go kamikazi on his ass and take us both down?
