That escalation league is fast approaching and I haven’t decided what to paint yet. So possibly starting with this list:
97 - Black Orc Bigboss, Shield, General, Berserker Blade
179 - 13 Black Orc Mobs
• 9x Black Orc, Shield
• 3x Black Orc, Great Weapon
• 1x Standard Bearer, Great Weapon
162 - 13 Infernal Guard, Standard Bearer, Shield
60 - 10 Sneaky Gits
498
Because that will lead into this list for an event in April that has a lot of interesting restrictions:
- No more than one behemoth character
- No more than one Level 4 Wizard
- Units not larger than 40 models
- Special characters allowed except for the Green Knight
- Mercenaries allowed
- No Allies
The custom scenarios are very heavily tilted towards infantry and many also require a banner to take objectives (some have 400 bonus VPs for objectives only large units of infantry can take). So this might be the ideal chance to go for a heavy Chorf list:
352 - Black Orc Warboss, Wyvern, Cavalry Spear, Enchanted Shield, Trollhide Trousers, Effigy Of Mork
155 - Daemonsmith Sorcerer, Wizard Level 2, Daemonology, Darkforged weapon, Daemonic Familiar
440 - Sorcerer-Prophet, General, Lammasu, Mace Tail, Wizard Level 4, Daemonology, Darkforged Weapon, Blood of Hashut, Armour of Meteoric Iron, Mantle of Stone, Talisman Of Protection
320 - 19 Black Orc Mobs
• 10x Black Orc, Shield
• 5x Black Orc, Great Weapon
• 2x Black Orc, Additional Hand Weapon
• 1x Boss, Shield, Berserker Blade
• 1x Standard Bearer, Great Weapon, Da Angry Ladz Flag
101 - 32 Hobgoblin Cutthroats, Shortbow, Standard Bearer
84 - 7 Infernal Guard, Shield, Detachment
482 - 19 Infernal Ironsworn, Overseer, Pistol, Hellshard, Standard Bearer, The Lammasu’s Beard, Shield
66 - 11 Sneaky Gits
2000
Now, for some explanations. The warboss is to take out characters and to assist with combats. The list is going to very heavily rely on being close together to take advantage of the beard in the early turns and Storm of Ash to protect it from ranged attacks. Daemonology works really well with combat focused lists and I would probably take double Steed of Shadows happily. Daemonic Vessel on the Daemonsmith is also a must take if it comes up. Gathering Darkness is also incredibly powerful with two sources of terror. The Lammasu is cheeky because it isn’t a behemoth but is still a large target. The debuff is also useful for culling enemy characters (which blood also helps as some of them won’t be able to do much damage without their magical weapons).
The black orcs are a powerhouse with Angry Ladz. I was originally on the fence about it but after using it I have seen the light. Whether quell impetuosity works on themselves doesn’t matter that much, if they get baited they get baited. Steed of shadows them into a better place or just munch down the bait. Berserker blade means the champion has 5 str5 attacks on the charge which is almost broken for a 39 point model.
Cuttthroats are solid gold for the points. Large target shooting should probably get a nerf 
The 7 infernal guard unit is shifty, I am not sure whether it can be done but the rule says you must have an infernal guard unit and that detachments can be smaller than minimum size down to 5 models. 7 is near perfect for taking a flank or just getting in the way and it makes the other units harder to chaff.
The Ironsworn are best with hand weapon and shield, IMO. Lots of AP1 attacks with a chance of getting boosted from magic. Plus 3+ in combat is very nice. They should be a great anchor for the army and they should be able to win the occasional charge or take a charge without melting. Hellshard on the overseer is the icing on the cake. This is a unit that no character will want to charge but with movement shenanigans they probably won’t be given any other options.
Gits are there for stalling objectives and taking out war machines/shooting units/etc. They are a huge glass cannon but those throwing weapons are stupidly good. Running around with 22 shots and sometimes hitting on 3s after marching is really, really good. People often underestimate them and I’ve found I can often kill things with shooting alone. They melt if faced with a stiff breeze but if something is turning around to face them then they have paid for their points. I usually always ambush as you get a turn of shooting whatever is still hiding on the board edge basically for free. Also, remember that they have evasive, it makes them even more annoying to deal with.

The list is leaning very heavily on magic, magic items and monsters but those are usually solid things to rely on. The issue is that infantry isn’t great so unless you give them a helping hand they can’t do much. And yes, there is no iron daemon because it’s too hard to get it in without weakening the infantry too much. 2 flying monsters, 3 big blocks (one that sometimes lands shots instead of fighting but still has an imposing presence) and a couple of support units should do nicely albeit a little fluffy and soft.
