Here is my recommendation on Karl's squad, but you will have to raise a unit or two:

[L] Griel (Legwand/Malice/Buffer + BC drop sphere)

Colt (Legwand/Malice/Buffer + BC drop sphere)

Yuura (Legwand/Malice/Buffer + BC drop sphere)

Ardin (Legwand/Malice/Buffer + BC drop sphere)

Shera (Dandelga + Evil Shard/Queen's Tear)

I think you should be able to recover all of your units' HP without Elmedia, Rigness, or Lucana thanks to Griel's HC drop buff. This squad should get you through Post-Graham and Treacherous Graham.

Post Graham is the hardest part of this GQ. Feel free to use all of your revives as Graham will do a fixed damage single-target attack that will surely kill one unit at the beginning of the fight and every 10 turns. Also, be prepared for when Graham reduces all Units' HP to 1 and removes all buffs at 50% HP. This is where you should use your Cures or Holy Lights.

Treacherous Graham shouldn't be very hard. Just kill him after the turn he remains idle. You can retry as many time as you fail the first time.

As for Seria and the summoner's squad, just make sure they can travel to the area next to the boss tile without any problems. xD
