Similar to Lantern, Pluto's ability, Good Dog, acts as ramp for this deck, allowing you to cheat out cards a turn early, or play extra cards during your turn that you otherwise wouldn't have had enough ink to play
When they arrive at the location they can still quest/challenge/sing/etc
From cards that can be used to unleash powerful effects to others that force players to get creative with their deck building, there are just some that manage to tick all the right boxes
Because youve exerted that card, you cant pay the cost again and cant use the ability again
