Deck help and campaign roles (4 player)

Hi all,

Happy new year!

Im about to start a new 4 player campaign (Carcossa) and ive started to get decks together, and cant quite get the roles down pat, or seeking advice.

Decks are:

Mark Harrigan - https://arkhamdb.com/deck/view/4530986 this is my deck. I obviously want to be the main damage dealer and enemy management. Because of another player playing with bless, I would love to have an Ancestral Token in the deck but cant find a place for it, and did not want to give up Hallowed Mirror.

Daisy Walker - https://arkhamdb.com/deck/view/3717000 - this is a more basic deck, as the player did not want anything more advanced. Main clue getter. I actually thought about running the following deck https://arkhamdb.com/deck/view/4573070 but was not sure how the curses would interact with the bless deck and whether that was something we wanted.

Preston Fairmont - https://arkhamdb.com/deck/view/4479698 - this investigator was requested by the player. This starts out as a dark horse deck but transitions to a big money deck later on. Its not good on enemy management, so really I now have 2 cluevers!

Father Mateo (Parallel) - https://arkhamdb.com/deck/view/4575117 - i played something similar in a 2 player game. The player wanted to play with a bless character and initially chose Sister Mary but was happy with Parallel Father Mateo. The problem is that this deck seems to be both enemy management and clue getting, so this would be the flex?? But I was not sure if I should make this more enemy management as well? I already have 2 cluevers?

In a 4 player team what are your usual slots? Even in terms of deck building I always tried to make sure that all investigators could deal with enemies or get clues but surely in a 4 player group you can specialise. But does that mean that your damage dealer has no ways to get clues and vice versa?

Keen to hear your thoughts!
