wp_query of ALL CPT regardless the taxonomies

Hello!

I have my CPT “Pack” with its related taxonomy “class”.

I’m trying to make a wp_query of ALL custom post types, this way:

$args = array(
 'post-type' => 'pack',
 'class' => 'class-1,class-2,class-3,class-4,class-5,class-6',
 'posts_per_page' => 5,
 'meta_query' => array(array('key' => 'featured','value' => '1','compare' => '='))
);

Now… It is rly necessary to declare all classes? Cause I want to show all cpt, no matter the taxonomy…

If I remove the taxonomy section, the wp_query doesn’t show any post.

This code only works if I put manually every tax term that exist.

Someone know a better way to make this wp_query shorter???

Many thanks!
