1.) A few (2) min sized units of death marks to counter deep strike, since the damn spiders can blink away even on their turn, I can at least chase them off of their desired targets, which will no doubt be the tomb spiders.
2.) Two harvest, if they are close enough to shoot me they are close enough to get wrecked in Close combat by a harvest and d-lord, they can hit and run away but that will be after I get a piece of them.
3.) use the salvos on the ghost arks to chase them off of objectives, and use the warriors in the arks (open topped armor 13 is as good an assault transport as you are likely to get) as assault troops to get at least a few wounds on them.

you guys think any of those will work, and do you have any other ideas?]]> http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8549996.page http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8549996.page GMT
I've found Scarabs are the best solution to dealing with Warp Spiders. The Warp Spiders most likely be in your backfield, therefore committing Wraiths to killing them is too many points in the wrong direction. (Wraiths have bigger fish to fry). Scarabs, however, are perfect for turning around and charging annoying Warp Spiders. Keep pumping them up with Harvest spyders and they should at least keep the Warp Spiders from doing too much harm. This tactic will only work against 1 unit of Spiders. If there's more than 1 unit then you may need to commit more than Scarabs.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8550361.page http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8550361.page GMT
As for scatter blink, I think the rule is whenever they are nominated for an attack, regardless of when it takes place. Its why they can be used to disarm snapfire boxes of tau troops, they declare a charge, get nominated for snap fire, then blink away. This ability is why five deathmarks is such a fun number, it's enough to hurt them, but not enough to wipe them out. So they can take the casualties (around 2 if the DM land within 12"), or get a taste of their own medicine by blinking away and not being able to shoot at their desired target.

As for how many units, last time we tangled he had 3 of them, each min sized.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8550503.page http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8550503.page GMT
Most people try to handle them with Mawlocs (not a shooting attack) and I think Nova powers but that does not help you heheh. Others will try to clip them with barrage weapons that target a close by unit. Otherwise they are a royal pain in the butt. Try to keep them away from line of site blocking terrain.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8550527.page http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8550527.page GMT LOS blocking terrain is probably not possible. If I push them off of an objective on my turn it's very possible they won't be able to return until their assault phase. If they jumped to the other side of a piece of terrain, 6" is probably not going to be enough to get them back on the objective, or let them get back into range to shoot at me. So it's very possible to keep them off of objectives with a small investment of firepower.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8550693.page http://www.dakkadakka.com/dakkaforum/posts/preList/685301/8550693.page GMT
