Should I build the Triarch Preatorians or Lychguard? Which weapons should I give each.
Welcome to the Dynasties! Magnetizing is a good idea, but for some context, the Heat Ray is the most common and flexible. In spite of Gauss, anti-tank is a challenge for Necrons and we don't have any hard-counters. Having a Heavy 2 Meltagun is nice and you can always use the Template profile if running up against hordes. The Particle Shredder is also worth considering. Pretty much all of our shooting is rapid fire and horde armies are a very tough match up. The codex just doesn't have much access to template and blast weapons, so it's good to take them where we can. I would avoid the Gauss Cannon though. Necrons don't really need Lascannons and if you want Lascannons, Heavy Destroyers are a better place to get them.
As for Lychguard vs. Praetorians, I'm a strong advocate of taking both, but you're only working with one kit for now, so:
Lychguard are an
HQ retinue and for that Hyperphase Swords and Dispersion Shields are the way to go. I would stay away from the Warscythes. Losing the invulnerable save is a huge blow to their survivability because they move slow across the table and will get shot to pieces before they can do anything. Plus, hacking away at something with 5 Warscythes is total overkill.
As for Praetorians, I love both builds and usually run a squad of each. The Rod of Covenant is your
HQ/Elite killer and the Voidblade and Particle Caster is your Troop/Fast Attack killer.
For your one box, I would go Sword/Shield Lychguard and expand to two more kits of Praetorians down the road to form a Judicator Battalion. I hope this helps.
