Support Cu Alter for Final Exhibition Quest

kinda struggling in this stage, even with all the SSRs i have. Cu Alter has decent survivability but none of my friends have him with mlb White Rose ce, which would help a ton. If you would be kind enough to add me, i’d really appreciate it. I have an NP 2 Shuten Douji, and NP2 Jeanne along with some other SSRs of mine. Also have an FSN Cu with mlb ce, may not be of much help though
