This is an obvious card for Mayor Kane. Since he can pick his classes, motivational speech (0) was a strong argument to go guardian. With this being neutral, it frees up deck builders to go for another color. I would argue a better and more surprising user is Patrice. It has good symbols, and it’s a free action and up to (seven, thanks Su!) saved dollars for a teammate. Plus, you’re more likely than other performers or civic individuals to draw it multiple times a game.
The drowned city investigator box doesn’t have a lot of allies with -> actions, so that effect will be minor unless you bring out Robert Castaigne or Dakota Gruffalo. Since it’s a parlay, that combination could let an ally play Dakota from their hand and engage an enemy on you, letting you have your turn unimpeded.
