Morvahna1 into Ghost Fleet

Well My personal Answer is Baldur 2. You deny all of his debuffs (outside of feat) If you bring sentry stones and manikins you don't have to worry about being boxed out ons scenario as much. You have lots of magic weapons and Crevasse which is an excellent rfp spell. Plus Your arm is so High that He just cant kill anything. 5" AOE's from the wrath will also murder skeletons and the long range and AOEs could feasibly wipe out a unit a turn. I personally think its the best match up we have outside of wurmwood (hellmouth just poops all over Ghost fleet and with spiny growth and some transfers wurmwood can actually survive a rifle assassination on feat turn. Remember Denny does not ignore stealth so she cant cast a debuf at what she cant see.

I think circle has the best solutions to ghost fleet honestly.

If you want to be a snowflake like me you could try the silly Mohsar Bones list Ive been working on. Use a warden and gallows to crevasse and a Woldwrath as an anchor. The fulcrum is also a great infantry remover and 2 units of manikins will mulch pirates. (the issue will be her feat with ghost shot pirate CRA's but better sentry stones than your caster. I think If you play it safe with Moh, use an arc node and manikins to get crevasses deep into his lines (scalple out some of the leaders and Rifles early on) you can really play a guerilla style of ranged attrition against it. I think the feat turn is going to suck and there are better options but it seems like it could be fun to me

Edit: here are the lists:
Baldur 2
Woldwrath
Woldwrath
Megs
2 Sentry Stones
2 Stoneshapers (free)
Wayfarer (free)

Mohsar
Woldwrath
Woldwyrd
Woldwyrd
Fulcrum
Stoneshaper (free)
2 Wayfarers (free)
Gallows Grove
2 Sentry Stones

I actually won a  local tourney using a Baldur 2 Moh pairing with only wolds (there was luck involved in game 2 though) You would be surprised how well The Mohsar list does into Jack and Beast spam just through sheer attrition with pillars its a lot more rounded out on the table top than it looks on paper. Curse can really enable your amry to beat on Heavies at range and we all know what will happen if a wrath gets a free charge on something.

My baldur list was different but I prefer the double wrath build now just for the natural spell denial. I feel My other list (while still really solid) doesn't hold up as well on a  denny feat turn. Otherwise I absolutley love it as a n alternate (now most people don't have 2 wraths) Here it is as well:

Baldur 2:
Megs
2 Wardens
2 Guardians
2 sentry stones
2 shifting stones
2 Wayfaeres
2 Stoneshapers

Its tanky and great into gunlines of all types. It clears infantry well and can even face tank some factions alpha strikes and arm 23 guardian will survive most standard jacks on the charge (even buffed) I still wish wardens were cheaper and they are honestly only in the list to help me distribute roots. It may not seem like it cracks arm but you can use shifting stones and RW to dictate how your opponent engages you and then gang up on his heavies to gain an attrition advantage.
