if this is only a quarter of it then we're not looking at an impressive city
this can draw you a lot of cards, and give you a two of actions. the thing that you want to do with it probably is have a bunch of cheap actions or just trash the things that aren't those. with reasonable trashing or one cheap action to get, you generally need about three to reliably draw all of your deck always, in my experience of two games. this is kinda clearly a strong card then, and it allows you to focus on the not-drawing cards you can buy.
-would you say the question of city quarter games is primarily how to enable it or is it how to make use of them once they're enabled? perhaps often you can accidentally do the first thing with the second thing
-what fun stuff happens because this is debt? have you had a bridge megaturn on turn 7?
-following that, how early do you tend to want to get it? i mean, it seems like you need actions for it to work but honestly +2 cards and +2 actions is probably fine at 8 debt
