Dammit. Still getting fatal errors.

Fatal error: Call to undefined function: bbcode_deck() in <snip>/includes/class_bbcode.php on line 1426

Dammit. I can't evaluate which line it is effectively at this point... your method didn't work.

$tag_list['option']['deck'] = array(
				'callback' => 'handle_external',
				'strip_space_after' => 2,
				'strip_empty' => true,
                                'external_callback' => 'bbcode_deck'
			);

Dropped that plugin into BBCode Fetch Tags.

require_once("http://forums.mtgdarkness.com/includes/bbcode_deck.php");

Dropped that into bbcode_create.

The bbcode_deck.php file is basically this:

<?php
function bbcode_deck($body, $name)
{
(working function goes here)
}
?>
