The Saint Pelin Patron abilities are focused on putting agents back on top of your deck to spam agent cards. “Pay 2 Power, Have 1 Agent card in your cooldown pile: Return 1 Agent card from your cooldown pile to the top of your deck!”
Your Neutral and Unfavored abilities are the same!
A strategy with this patron is to acquire agents from the tavern, because these go to your cooldown pile, and then returning them to the top of the deck so you can use them that turn or next! It’s a great way to stack your deck.
