user24909: Suppose white gets the following opening:
[FEN ""]
1. e4 e5
2. Nf3 Nc6
3. Bc4 Nf6
4. Ng5 d5
5. exd5 Na5

This is what I call Fried Liver Refuted, instead of Nxd5 we get instead Na5. From this position does white have some tricky continuation? By tricky I mean some sharp snappy line with some traps in it. It seems like after Na5 white runs out of tricks, but is this true? Some tricks in this position would be really fun to implement; most players only study this line up to this point because it is preached that Na5 is the best move for black and after it white runs out of punches, so a couple of tricks would most likely find black with is guard down.

user924: I believe you should go for 9.h4 in the main line:
[FEN ""]

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Na5 6.Bb5+ c6 7.dxc6 bxc6 8.Bd3 Nd5 9.h4

White is trying to keep his pieces on active squares at all costs.
There is a lot of complexity here, e.g. in the line 9...h6 10.Qh5 Qf6 11.Nh7!? Rxh7 12.Bxh7 g6 (don't play 11.Nxf7 hoping for 11...Qxf7 12.Bg6, black has 11...Nf4).
The line 9...Nf4 10.Bf1 h6 11.Nf3 Bd6 12.d4 exd4 13.Qxd4 Ne6 is not as tricky, but white has a pawn and Stockfish says white is a little bit better, which is all you can hope for these days.
In both cases, preparation will help, as there are no normal moves in positions like this. And that's the only kind of "tricks" that are available here I think.

user24693: I mean, this is the main line and for a reason.
But I would be very surprised if most people's repertoire ended here, this is where it begins. The line goes
6.Bb5+ c6 7.dxc6 bxc6
And now White has a number of options. In all of them White stays up a pawn however Black gets some counter play. (and there isn't a great line to give back that pawn for initiative, not much to play for tricks)
The two main moves are 8.Be2 and 8.Bd3.
The line might continue 8.Be2 h6 9.Nf3 e4 10.Ne5 and Black will keep some lead in development and try to attack.
The idea of the other move then is to gain access to the e4 square, if 8.Bd3 h6 9.Ne4.
However this move blocks the d pawn so White will need to move that bishop again at a later time. Both of these lines can be very complicated and sharp so White has to be careful.
