Discussion: Winning list at the Seattle GT

I followed a random link the other day to a blog I'd never been to, and discovered the Purgatus has his own blog now (I don't read YTTH much anymore, but I'm assuming Stelek got sick of him posting 3 times a day :-p).  I read a little bit, and found a few mentions of his GT experience at Seattle, which was a little interesting.  Anyways, all talk about Purgatus aside, I wanted to present the winning Seattle list, and give a few thoughts on it, though mostly open up the floor and let others chime in about it.

Cool, here's the link to the post, it's the 3rd army Purgatus played.

I'll type out the list, for those too lazy to go to the site, lol.

2000 points of Marines

Vulkan

10x Assault Terminators w/ 4x Lightning Claws, 6x TH/SS
10x Assault Terminators w/ 4x Lightning Claws, 6x TH/SS
Techpriest w/ Harness, Power Weapon

Tactical Squad, Multimelta, Melta, Combimelta, Power Fist
Tactical Squad, Multimelta, Melta, Combimelta, Power Fist

Land Raider Redeemer w/ Multi-melta (and I presume Extra Armor)
Land Raider Redeemer w/ Multi-melta (and I presume Extra Armor)

This list is somewhat intimidating to me, since it's hard as hell to kill 10 Terminators, and even harder to kill 20.  And once you do, you've gotta kill 2 Land Raiders, and the Tacticals, and Vulkan.  A very steep order, if you ask me.  So, what beats this list?

A few things that I can think of off the top of my head: 

•  Any other Vulkan list with deepstriking speeders or Melta Attack Bikes that could kill the Raiders, and then run circles around the terminators, picking them off slowly.  Libby w/ Null Zone would for sure help.
• Double Lash, lol.  Seriously, this would be the perfect matchup for a double lash player.  If any actually existed these days.
• Dark Eldar skimmer spam + blaster trueborn + incubi to mop up
• Dark Eldar Wych spam ('wych' I hate to admit lol, since I don't generally like wyches)
• Some Eldar lists as well, if you kept moving
• Maybe Tau?  If you destroyed the Raiders fast enough, and had enough ninja suits to JSJ?  Seems doubtful to me though.
• Blood Angels with an expensive Death Company, or other power weapon spam list
• Black Templars with lots of Furious Charge LC Termies in Raiders (maybe)

Still, it's an intimidating list, to me (which I almost never think).  Tough to kill that many tough guys.

What do you think?  I want to know what people's honest opinions of this list.  It seems flawed enough to me that it should come up with a bad matchup, yet it won a GT.  How would you play it?  What would you do if you had to play against it?  It's been messing with me, ever since I saw it posted up.  Let me know!
