Why does wildcard mask do more than subnet mask ???

What do you mean exactly?

In which case? And what should be different?

What does wildcard mask bring more than subnet mask ? Why subnet mask is not self-sufficient ?

wildcard-bits and subnetmask are two things.

 

IP+Subnetmasks = Range of Subnets

IP+Wildcard-Bits = Range of Hosts

Subnet masks must be contiguous; wildcard masks need not be. This makes them useful in some ACLs, e.g. to create exclusions for a particular address offset in a number of subnets.
