Note:This reception is purely for fun and will cause EXTREME lagging. I hope your device is enough to handle the lagging.

Report to me in the comments all bugs you find.

To invite the ultimate battle:You will find the reception at Hana as the third part of the story. It can be otherwise entered using Book of Xiao and Book of (whatever name Yan's is) 
Once you start it, the wave information should show Finn and Finn alone. Just begin stageplay.
If you find Finn flying around randomly around the stage, you will know this mod works. 
Now carefully kill him and the real challenge begins.

Basic rules
1.The enemy team consists of 12 waves (if you don't count the poor Finn in), each will only show up once you cleared all enemies of the previous wave.The first 5 waves are ALL guests (mostly one of each diferrent enemy) from the respective chapters.
However, the 6th wave is SotC's first and second levels (which is 9 receptions worth of people in total, RM excluded) and the 7th wave is whoever that's left in SotC.The remaining 5 waves I won't spoil for you, just try to survive long enough to find out (or you can use some cheats, I don't really contradict that).

2.All enemies will enter with some bonus emotion level and page draw. This is to prevent them from simply doing nothing or becoming practice for your coolest AoEs.But don't worry, as your librarians will heal up and draw too once you finish a wave.

3."What happens if all my nuggets are dead?"you may ask. Well, perhaps they are not all your nuggets after all.
 Once you fail in Keter, Malkuth an her gang will join the battle with the above mentioned bonus emotion level and page draw. 
Team emotion level will be reset, of course, which means you get to choose new Abnormality Pages and E.G.Os after this round. 
Your E.G.O from the previous floors will still be usable for once only.
The same will repeat until you run out of floors. What happens next?
