Upd.: P.S. Note time complexity difference: mergesort is O(N log N), Fisher-Yates shuffle is O(N).

I would consider this as a major deterrent. As well as the point made by the other answers.

Since you touched the subject of unorthodox shuffles, perhaps you also want to consider shuffling by converting the array into a hash and back again. For example:

my $pseudoshuffle_with_hash = sub {
    my( $ref_array ) = shift;
    
    @{ $ref_array } = keys %{ {map { $_ => undef } @{ $ref_array }} };
    };
