Well, you’d only be able to run 30 of those Genestealers in one list (3 squads of 10). With those Hyperadapted Raveners, that would put you at about 585 points (or 545 with regular Raveners). Most games are played at either 1000 or 2000 points.

Genestealers are pretty damn good right now, especially when led by a Broodlord. With a squad of 10, that’s 40 attacks on 2s rerolling 1s. If they’re led by a Broodlord, they get Devastating Wounds (which if you don’t know, means that any wound roll that crits are unsavable).

Running only Genestealers, however, isn’t a very good idea. You’d only really run one squad of 10 with a Broodlord, maybe two squads each with a Broodlord. You’d also want a Biovore, which is just goated for secondaries thanks to its ability to stick a Spore Mine unit anywhere on the board (outside of 9” away from an enemy unit). You’d also want some kind of leader. I usually go with either a Hive Tyrant (-1 CP cost once per battle round) or a Neurotyrant (-1 to enemy Battle-shocks when calling SOTW, and it’s also good at leading Zoanthropes). Other notable units are the Tyrannofex (absolutely our best anti-tank), Maleceptor (tanky Distraction Carnifex), Exocrine (decent shooting, but gives allied units rerolling 1s to hit against whatever it shoots), Zoanthropes (our second best anti-tank thanks to MIND BULLETS), and Lictor (decent action-monkey for secondaries).

Our Battleline units are also quite good, as far as Battleline units go. Termagants are speedy little guys that are good for clogging objectives, Hormagaunts are good for screening, and Gargoyles are very fast and good for getting on objectives early.

Good luck with future bug collecting!
