Making a card deck of spades only.

I'm trying to make a card deck for Alien RPG that is just 10 cards. I looked at the wiki and I understand how to start a new deck but it wants me to add my own images. I just want the spades suits 2 through Ace. I can't seem to figure out how to edit the 54 card deck that comes standard, or build a deck of just the spades using the roll 20 cards. What am I missing? Thanks Mike

open the standard deck and scroll down and duplicate the deck.  Then edit the duplicate by deleting anything you don't want.  Rename the deck to avoid any confusion. ;-)

Excellent thanks!
