Recording or selecting a snare sample that you like the character of can be fairly straight forward however getting it to cut through the mix can be really challenging. 

I find that if you layer it with white noise it can really help it stand out. 

The trick is to shape the white noise amp envelope to suit the transient of the original snare and then balance the level to sit just under and fill in the frequencies. 

Later you can always add further processing such as EQ but by this point you should find that it’s a strong enhancement.
