[Team] Not Sure How Good My Teams Currently Are (NA)

Here's my box currently and the teams I currently use are

• Liu Bei / Claymore / Echidna / Renji / Leilan, with a friends attacker enhancer
• Leilan / Liu Bei / Echidna / Keeper of Gold / Chocobo with a friends Leilan
• Sakuya / Claymore / Chocobo / Liu Bei / Maeda Keiji with a friends Sakuya (The problem with this team is that I can't beat the descended carnival with Zhou Yu, so I can't get her to be awoken) The hardest dungeon I've beaten is this weeks challenge dungeon at level 5, as well as a few easier descended dungeons like Goemon, Hera, Zhang Fei, Tengu, Ect. (All on Legendary). I was wondering if you guys saw any better teams based on my box, and also if there was a team that you think I could use to beat the arrival carnival in descended carnival (Legendary) to get Zhou Yu. Thank You! :D (btw team cost shouldn't be a problem as I can probably just rank up to whatever cost I need)
