So to conclude. Zoro didn't:
1. Use King of Hell Style
2. Use Excessive amount of CoA/ Green Smoke
3. Use Multiple named attacks
4. No Bandana Powers
He instead:
1. Used Base 3 sword style
2. His usual CoA haki
3. And 1 new named attack
Holy L for Lucci. He used a Stronger form than he did against G5 Luffy and also used a stronger thrusting attack "Madara" against base Zoro.
