How would I go about trying to display a custom field for a club in a template? Specifically on the club card.

Sort of worked it out

{{foreach $club->fieldValues() as $fields}}
	{$fields['field_1'] )}
{{endforeach}}

 

$club->fieldValues()['field_1']

Would be a better option. You don't need to loop over the values, and field_1 would be the key not the value.
