List Pairing

In my opinion (and I've played this pairing with not too-dissimilar list in a few national events last year), you're in for auto-losses against most competitive lists in the current meta. At least, in the sense that you will have to outclass your opponent play level (and/or training in the matchup) if they're dropping competitive lists. It's not technically auto-losses, since against Legion, a lot of silly accidents tend to happen to wardudes on the field
Good players will recognize this as their only loose condition however, and will never give you the chance.

Also, sadly, in Legion today, if you don't play Kallus1 jam nor Absy2, you're going to struggle anyway.
But that's not really the problem, you play Legion for the fun and the flair

Lists that I have found will make you wish you didn't play this game:
- Harby, with (hopefully only one) judicator, with or without a pair of archons. Nothing much to say here, she just outclass you in every game aspect, and has 9 shield guards (which at least you won't mind to much with all your sprays, but they tend to screen correctly in melee too). The judicator removes the Blightbringer in 2 turns of shooting, or one heavy per turn. She recurses, you don't. Golab is your master piece, but he can't be everywhere (especially since he need to be in cover/out of judicator range).
- Garryth2 will debuff you and shoot you to death with uncatchable tridents. It's one of the most enjoyable bad matchup, since you usually can remove his melee jam unit and destroy a few jacks, which gives you something gratifying to do. At least you've got Banishing ward on the Blight Bringer.
- Zaal2 with also let you break a few stones before hitting you like a truck, while being near unvulnerable next turn. Also almost anything Skorne with a turtle (or two) will probably just out-attrition you on the long run. I don't like Skorne so it's probably mostly personal, but it's certainly the less enjoyable of the matchups.
- Tharns. You don't have the volume of attacks or enough grievious wound to counter Tharns. The LotF can still almost kill a BB or a throne by himself (but he won't bother if he can take Golab instead). All the undying characters (death wolves, brigitte & boy) will cost you so much to remove you won't have any attack left for the BG or the surviving tharns.
- Dreamer with a bunch of heavies. Any beast-heavy grymkin list in fact. Even post-cockatrix-nerf, all they ever needed to beat us were 3 cage rages to tank us and 2 S&M to kill our 2 heavies in one turn. Dreamer just tends to do it better. Usually comes with a bunch of incorporeal solos to hold scenario but you're a little better off with your naga than me without.

There are a lot of bad to very bad matchups elsewhere but those are the one that came back to me each tournament, and felt especially one-sided.
Me and my other Legion friend have designed lists that have a fair chance against each of these, but you can't bring 6 lists to a tournament.

So I usually hope for first turn then put a lot of caster kill pressure on the opponent and hope they're noob enough to be afraid of this and let me score up on scenario before I have nothing left. Then sometime in the heat of destroying my army they forget about caster kill again and I win the game. I feel most at ease for this with the twins, so they're usually my default "do your worst" drop.

Still, don't let my post discourage you, there are also a lot of other sub-factions which will give you fun games in the middle tier of tournaments.
And Legion is still one of the funniest faction to play with (outside of Kallus1 jam or Anamag ogruns).

(also note that I play in a small national meta, where you're garanteed to play WTC-level players as soon as you go in the top half of the rankings, and I for myself train less and less with each passing month... when I don't play in tournaments with WTC players I actually tend to win the tournament )

Yeah same here, no interest in Kallus1 as he is now. Played him a lot a in mk2 when he was more enjoyable (pot, lessers, good animi to put on warriors, more support for minions -> Kallus1 full-warrior wasn't just run-jam-die-win-on-scenario at the time).
I think the list I'm seeing most is the official JVM Kallus1 primal terrors ? Take BlightBringer, 2 full chosens, 2 full chickens, 2 hellmouth. You can also play it in Ravens, replace chosens with raiders. Not sure which one is best (probably terrors ?). Just run everything on first turns and try to jam opponent out of the zone with an army he has to kill twice. Everything that survives hits great in melee with his buffs, and just tries to remove key pieces and buy time.
It wins a lot of game (scenario or clock). I've seen it played once or twice, looks like it's boring as hell. But it wins games.

Absy2, I have the same problem has you do. She's just strong and efficient in a lot of matchups though. And she has really silly assassinations. I like the list the guy brought to the WTC finals last year, with 11 lessers in ravens - very refreshing and efficient. Probably the best candidate to get a mecanoshredder when it's out.

Fyanna we play in Ravens/Terrors here, with flying BG (including Golab), and chickens, hellmouths. Really enjoyable and chickens actually get a lot from her, and are very good to jam fast under feat. Anyway she's cool on the table.

Lylyth1 might feel a little linear by herself, so I tend to play funny independant models with her (raptors, thrones). I think she is one of the best counters to immortals list in Skorne (of any BE-heavy list), if you take her with 2 thrones, 2 naga, 2 carni. Just shadow bind the BEs, erase infantry with thrones on feat turn (beware of arcane vortex for immortals), and send carni in parasited BE/colossals.

Everyone should play with Kallus2 once too. Just see how far you can caster kill. My record is 22" with golab (after a 20" headbutt from the raek).

If you want to have the most fun, I'd say pRhyas. Another future fan of mecanoshredder. Her feat is nuts. With Proteus and 2 thrones, it's hilarious. The joy (and stress) of having to send your fury5 ARM14 warlock do the heavy lifting multiple turns in a row is... exhilarating She's my favorite counter to Garryth2 too (I'd say 50/50, depending on dice and scenario).

Have (responsible) fun with your Legion
