This should be:

    $ print ${testvar/%var/Replaced}
    This is my test Replaced

The leading '%' indicates that the match must occur at the end.

If you don't need it done in a single line, you can always use "case":

counter=0
for number in {1..100}; do
    case $number in
    *0) print "Hit a ten! $((counter++))" ;;
    *)  print $number ;;
    esac
done
