Arle E > Bennett EQ > Xilonen E N2 > Citlali N1 EQ > Arle CA (wait) N2W N2W N3D N3 > Citlali N1 > N2W N2W N3D (N3)  
melt sequence: CA C2 Aa aA aaA aaA - Aa aA aaA (aaA), capital letters are reacted hits  
2\[N2W\] 2\[N3D\] lines up the ICD to melt the N2 and N3, which have higher scaling than N1 (if you're just doing N3D+wait for example)

The reason this works is that citlali has 3 instances of cryo app that you can utilise for melts;  
Ben Q applies 2U pyro > Xilo EN2 and Cit N1 E (or E N1) wipes the pyro, leaving no aura > Cit Q applies cryo > Arle CA melts > Cit E storm applies cryo > Arle C2 melts > Cit spiritvessel skull applies cryo > Arle N1 melts  
Sucrose EE or E N1/Kazuha tEP can fill in for xilo if you don't have her, works the same

Arle Swap + CA must be done as fast as possible, otherwise you just apply pyro with the CA+C2, I've found the timing to be lenient enough to use in actual gameplay and not just showcases, even on 300 ping i can get it quite consistently  
If you don't have C2 then it only becomes easier, you get 2 cryo app instances that pretty much guarantee melting the NAs if done correctly  
(if you have her sig) doing this also means you don't need to CA E and then cancel your CA when starting your NA string, leads to better whimsy stacking
