Well, if you mainly are hunting for Treasure Tickets & Hidden treasures, the consensus is that the medium field (Garden Paradise) is the best, my collected data supports this as well. While the 30 ticket runs have a lot of Custom skill items (recipes, skill cores, celestial Water, refinement M) - which you don't have any use for yet - it also features Awakening items (Orbs & stones) - but those can be gotten from Elemental Hall. The other reason for doing 30 ticket runs is to get any of the old UR LAWs Celestia, Dark Succubus, Hiraga, Jeanne D'Arc or Sacred Amaterasu - I'm guessing these will be replaced Sept. 11th though since the Legendary summon lineup is renewed (see in-game news). Rate seems pretty high accually, I've gotten 3 URs from 22 maps. As for Jodie & Mirror Maiden (UR) as well as Mirror Maiden Shards can be obtained from the 290-map. While the 90-maps can drop Premium URs.

Regarding Archwitch Cores: I only use then for Guaranteed UR tickets. They are surely your best option as well.

Ymir is a really good card, useful in duels & in Tower events. But as far as improving you ability to rank in normal AW events between the two Fujisan is superior when it comes to grinding Elemental Hall for points.

On a side note, don't waste any Mirror Maiden UR on an unleasher (unless it's a unleash all). Safe it for a really good card, like that 600% buffer you have, better yet a Multihitter. User blog:VeiRetning/What UR Cards are worthy for Mirror Maiden? & User blog:VeiRetning/How good is my Guaranteed UR Ticket Draw? give a quick reference about worthy cards, keep in mind it depends on what you need to improve your game.. an unleasher doesn't improve that much as when awoken.
