FOR A PARTY ENVIRONMENT (not so much nightclub):
A cool opener is to go up to a girl and say as seriously as possible, while rubbing your nose and looking very dodgy
"Do you..do you do cocaine?"
they will (generally) look sort of worried and be like "..no?"
Then you smile and become relaxed and say "Haha me neither. Kevin Rudd, and your name is..?"
the idea is for it to be funny though, i find that 90% of the time the person will laugh and be like "Hhaha you had me there for a second!" then happily shake your hand
(youve already kinoed once)
Then from there you just comment on how good or lame the party is;
1) " Pretty smashing party, huh?" if party is bad
or
2) "Ive gotta hand it to , they can sure organise one epic get together" if the party is good
from 1) you can then either be serious and comment "Now, what this party needs is better music and more related guests. SPAM noone knows each other, so its flat"
or you can joke and be like "Its nearly as good as my cousins birthday last week! She just turned 11"
from 2) you can say "How do you know the host?"
etc etc, just make conversation.
After this initial stage, just start talking about her. Be like "I bet youre more interesting than this place, tell me about yourself. What are you studying?"
you can take a stab in the dark and say something like "You look like a media student

"
Because if you guess correctly, she will think youre amazing.
If not, then either joke about how you made the mistake or just keep talking.
Its important to be casual as, dont face her or block her off. For example, if shes at the bar, just lean against the bar while facing the party, half facing her.
Then, as soon as she says something you can relate to, BAM! show her that youre interested in that same thing as well, act enthusiastic, and face her with your whole body. Act as if she did something great (ie she likes Daft Punk, and so do you) and now she deserves your full attention.
Then just say "This is awesome! lets go sit down"
She will follow you if shes not intimidated and is having fun.
From there keep kinoing when you can, doing it condifently.
Slow down your conversation pace and escalate kino, maybe talk about something deeper, or do the opposite and tease her while kinoing, being super playful
Kiss her when ready.
NOTE: Im no expert man, im just a guy whose gotten into the game recently and has a slightly better than the average male shot at picking up. Ie, if i go to a party theres a good chance ill get with a girl if i try, but im not full on amazing and this wont always work.
Its important to understand that this is my style, I just act friendly and unintimidating (basically so she likes me and thinks im fun, not necessarily "Sexy") and then i become "sexy" when i isolate her and escalate kino.
So dont know if this helps, but this is the way i do it

Magic tricks are also great ways to impress (just learn one good one and show if you run out of conversation, as it sparks more conversation and depending on the trick can require you to kino)
There you go!
