Scalpel Formation value

Bearing in mind, I find Wracks to be a terrible unit choice and don't suit my playstyle at all, so they will probably just end up trying to camp 2 objectives, does anyone consider 100 points (the Wrack cost) of value to be able to Null Deploy in the unlikely event (my meta) of coming up against a Droppod army or something similar that can assault me first turn with no comeback? I see the D3 First Blood thing as a small and unlikely bonus.

I played against Eldar yesterday and got beaten to the starting roll, so was destined to go second. To avoid being tabled before I got to do anything, I deployed a single Lhamaean behind LOS cover, knowing he would survive turn 1. He died turn 2 and then most of my army came on the same turn. I tabled the Eldar player at the end of Turn 7. Isn't this the same idea(l) as [near]Null Deployment?

You tabled him? What did he take what did you take and what did you do?

He was using the old codex. It was the last game in a 4 month league. He had 3 Wave Serpents, 2 units of Wraithguard, a Wraithknight, a Crimson Hunter, a Spiritseer, a large unit of Dire Avengers and 2 units of Guardians.
I took the DA formation, which killed 1 model and then died (lol). 3 Venoms with Kabalites, each with a blaster. 1 Razorwing, which chased the Crimson Hunter and made him jink every single turn. 2 units of HayScourges. 3 Ravagers, 1 of them 3x Dissies and the other 2 with Lances. As always, a single Lhamaean.

I just won by out positioning him and otherwise, we just had a shootout

But I guess you are right about the null deployment thing. But only if you can be sure to survive. I wouldn't try that near null deployment against guard.

The minimum cost of 230 points (wracks, Venoms, and mandatory venom upgrades) is a steal for the Scalpel. The option for total Null Deployment is immensely powerful in my opinion.

Still spending 100 points on 10 terrible models. You think 100 points is well priced for the option to null deploy?

Easily. Those models are also quite durable. You can easily Null deploy entirely (even if you went first) without fear of getting tabled turn 1. An Ossefactor can be a big help in picking up those potential extra VPs, too.

I take them in every list with the points for them, and I've never regretted it.

In that case, I'll give it a go :-)
