My battle pet has the following stats: Level: 2430 Health: 10260 / 10260 Strength: 9950 Defense: 6510 Speed: 6510 Intelligence: 3722 AP: 232 Tier: 13

However, I'm still unable to rack up more than one win against Lukien.

My base weapon set is: Volatile Energized Mecha, Soma Tablets, Swashbuckle, Cronus Blade, Maniacal Slappy Hand, Phoenix Quill, Rainbow Vortex, Reviver of the Lion.

My scrolls are four Shriek of Despair, two The Void, one Triple Threat, two Gift of the Forj, and one Holy Deluge.

What changes can I make to get up to five wins?

you can lose the Cronus Blade as Lukien doesn't deal much magma. The Slappy Hand is good but what you need is Maniacal Essence and a Recycle Blaster. You're not blocking Lukiens' dark attack (his main attack icon) so it's pretty much imperative. I am suggesting the recycle blaster to replace the Rainbow Vortex or the Slappy Hand. He can't be frozen so you don't need the Shriek of Despair freezing scrolls.

Start by using Soma + Recycle Blaster and a Void scroll, the sooner you zap two of his weapons the better chance he'll use one or both of them. This gives you a chance to heal. Your second move should be Maniacal Essence and Volatile Energized Mecha + Holy Deluge scroll.

After blasting two of his weapons and using your Energized Mecha use your Swashbuckle and Maniacal Essence with your Holy Deluge to finish. If you still find it impossible try modding your weapons to enhance your chances.

For some reason I've never considered the Recycle Blaster, and didn't think about switching out the order of my scrolls...both game-changers. I'm probably not getting a Maniacal Essence until the next Jelly War, but I've got my five wins now anyway. Thanks!

Soma tablets and Recycle Blaster do not work against Lucien, he has hundreds if not thousands of weapons equipped.

I used ME + Mecha round one, then ME and Swash for thhe rest of the battle when I wasn't healing. I have 5 healers/blockers equipped.

also attack EOR or marquise mods are super important.

I do not know if I can ask here! What do I do if I not have the Swashbuckle ? What should I use instead? I have the ME and the trident.

use what you have. If it works it works, if it doesn't buy what works or train.

Did you get the wins by following what Nickel said? I have 2 tier 13 slightly different stats to yours that have only gotten 1 win. I may try it

I did! I didn't use the Maniacal Essence (don't remember which one I used instead, but something that blocked more dark), but opening with Soma Tablets and Recycle Blaster and reordering my scrolls not to prioritize freezing was enough to get me to 5.

Awesome thanks I will give that a try I have 6 challengers yet to defeat
