I finished home one 5 star a few days ago. Currently the only one in my fleet who will be able to get him, rest either dont have rebels on the home one to 5 star.
Here is my roster: https://swgoh.gg/u/lakson/
As you can see, our rosters differ by very little. I would suggest getting ashoka ship, but it's not a hard requirement because you can use consular as well. Maybe consular is even better because this fight is all about dragging it out.
I was going to keep my strategy to myself since it took me HOURS over 4 days to get it done, but you aren't in my shard so I got no problems helping out.
Getting ready: Pilots do not matter as much as ship levels do here. You need raw survivability, and ship levels improve that a lot better than heroes piloting them. I still made sure most pilots I used (save for that cassian wing that can use an assist and get one shot after no matter how much I invest in him) have 5 star mods for the fight. Some had 4 stars.
Mill Falcon was vital in my strategy to win. His damage is just over the top compared to all other ships of same level/stars, especially at 4 stars. You still might win, but I cannot guarantee that without Mill falcon, because you need AoE.
Step 1: Focus on burning ashoka. Her dispel is going to hurt you a lot. But she is the only one you burn.
Step 2: Make sure your phantom gives everyone the crit buff. You need to be buffed for Calamari Barrage and Ghost assist ability.
Step 3: After ashoka is down, focus one of the Sergeants, then the other, then the third (if present). Note: DO NOT KILL THEM. Burning their protection and getting them to yellow is enough. One hit away from death is ideal, but leaving more hp will still work. Reason 1: Once their protection is down, AI switches to regenerating it instead of burning your ships. That means consulars will use their prot up, as will sergeants. That is a lot of missed turns for the enemy, missed turns that will eventually score you a win. Reason 2: If you just do the arena strategy, Mace will out-reinforce you. He takes turns faster, he has stronger ships, and his sergeants which he has at least 3 in reinforcements will burn your ships faster than you can burn his. Having 2 consulars and a rex up makes it possible. Fighting 4 sergeants at once is not.
Step 4: If Mace reinforces with a consular, your chances of winning just went up, bigtime. I managed to do it with a sergeant reinforcing, but consular fights were a lot easier, I have not used this strategy at that time otherwise I would have done it without so much mental trauma.
Step 5: Once the enemy team is all in the red/yellow, You either use the barrage again or master plan the Ghost "attack on all angles" on a double tap. Getting Ghost to do it was tricky for me because most of my ships are down by the time he takes 5 turns. With your consular, you just might do it. And you lack the Mill Falcon AoE so you pretty much must do it.
Step 6: At this point you turned a 3v5 into a 3v2, possibly 3v1. If you managed to finish them all off before Mace reinforced, you won. You go for burning a single target now. With a bit of luck you will get your Calamari shards, but the worst is behind you.
Good luck to you. Tell us how you did!
