Hi there, it's an easy choice of Mirroring Gilgaesh, Amalgating her and Awokening after that.

You mentioned progression thus I would assume you will want to progress towards the current Game Meta, which basically for the AW Event, is farming points in Intermediate Difficulty Elemental Hall using Multihitter + Salvo Teams of the same element and having 3 of such teams per element, which means a total of 12 teams across 4 elements!

A Sample Ideal Team of the Current Meta for Intermediate Elemental Hall farming is something like

1 X 10x(Or higher) Multihitter that can Awoken Burst 1 X Salvo 1 X Buffer 1 X Awoken Burst 1 X Team Unleasher

With all card above being able to awoken burst and the same element as the Elemental Hall Day except 1 card(Not the Multihitter/Salvo) to be off-element for slowly tapping the enemy till your cards are setup and ready to deal maximum overkill damage to the enemy(For maximum Subjugation Points). A team like the above earns around 1.1 million Subjugation Points before any point boosters.

I see that you mentioned the multihitters you currently have are (Hrungnir/Rapier Princess). By getting Heroic Gilgamesh, you have a better advantage also pre EH open as you are able to do 10 million overkill(With Heroic Gilgamesh) compared to 7 million overkill(With Rapier Princess) thus earning you more Subjugation Points as you play :)

Chainsaw Girl Chainsaw Girl is a good candidate but definitely not as good as Gilgamesh. Also, you already have some buffers like Summer Alchs/Superstar Mikas, this make her not as high priority. She can be considered if you have extra Mirror Maidens and no other 9x or higher Multihitters or later on when you need a Cool All Element Buffer for your Cool Element Teams.

Hiraga As for Hiraga, she is not worth mirroring because she is kind of available for "free" at the moment in the treasure hunts but that doesnt mean she isnt useful, just not as critical. As highlighted in the above Meta Sample Team, you would need 3 Salvos for each element, thus both Hiraga and Divine Panacea are part of the pieces of the End Game Team you would need to assemble but their uses will come much later on since you need a team of the same element to utilize them well.

For now since you are building up your team, going for the best upgrade, Gilgamesh in this case, works best for you :)
