I can't tell if the <readmore> tags are working
Yes, the <readmore> tags are working.
it would be good to get feedback on logic, style, most anything, really

As others have strongly hinted, only a single array is necessary. What you have is overly complicated. Rather than answer your pointed questions, consider the following code, which is really tilly's approach: 

use strict;
use warnings;

my @cards;
for my $suit (qw(_clb _dmd _hrt _spd)) {
    for my $rank (2 .. 10, qw(j q k a)) {
        push @cards, $rank . $suit;
    }
}

for (1 .. 10) {
    my $index = int rand scalar @cards;
    print splice(@cards, $index, 1), "\n"; 
}

Although the instructions do not explicitly call for using splice, it really is the right tool for the job of preventing random duplicates. Each time through the final for loop, a random element is removed from the @cards array.
