==Allied Armies==

As for the GHB 2017 Deathrattle can have these allies: '''DEATHWALKERS''', '''DEATHLORDS''', '''DEATHMAGES''' and '''SOULBLIGHT'''.

First off, unless you're doing something very fluff-heavy, there is no reason to take an allied force of Deathwalker (zombies) or Flesh-Eater counts.  Both of these are horde armies, for the most part, and have even weaker hordes.  So there is no reason to put a tarpit in front of your tarpits.  If you're thinking of doing this, just use more skeletons instead.
Nighthaunt could be a viable combination.  But most Nighthaunt units are putting out mediocre attacks while absorbing decent damage, which sounds suspiciously like a bunch of skeletons with a banner.
Deathlords are a decent option, but are very expensive and really cut down on the number of skeletons you can bring out.  But in a large game, say, 1500 points or more, this is a pretty solid combination.  But what you really want is...
Soulblight.  Going back to their Vampire Counts days, a vampire lord or two will be a great addition.  With their strong casting and solid fighting, they could be used in place of a Wight King.  Use these guys more for summoning, and let your opponent drown in bones.  Put the vampire lord on a zombie dragon and use him to fly around to wherever your skeletons are looking weak.  Chomp some enemies, summon some more skeletons, and that should hold them off for a while.  In matched play, you will obviously need to be a little more conservative with when and where you summon the skeletons, but holding a couple in reserve for the Vampire to summon is still a pretty good idea.  Put the vampire lord on an objective, summon a unit of skeletons for tarpitting and reinforcements, and revel in the butthurt.
Deathmages are a cheaper version of Soulblight when used with your deathrattle.  They have none of the actual fighting capability, but being a good deal cheaper you can take a few more skeletons (or another necromancer).  With their Dance of the Macabre, they can really boost a unit of skeletons.  Place a few necromancers behind a horde of 30 skeletons with a banner and you can chew straight through most common enemy troop units.  With their already high number of attacks that are improved by the necromancer, this unit is especially effective against enemy tarpits.  Throw in their shields which will give a nice save bonus against the kind of weak, rend - attacks that an enemy horde is probably throwing at you, and the banner to revive some of your fallen troops and you should be set.
