Lucky Find is indeed strong, its a Sure Gamble plus a $2 click, with a lower starting cost requirement. The 2 influence is pretty important as a balancer, or else we would just see 3 of it in every deck. I think it will get some play, in decks that can spare the influence. At 1 influence it would probably be auto include in practically everything, and then runner economies would just tend to converge onto Lucky Find + Sure Gamble + Daily Casts + Dirty Laundry + something else, with almost no variation.
Quandary's flavor text is hilarious. It wants to have two subroutines when it grows up! I guess it grows into Enigma. Original netrunner had a code gate named Quandary: Strength 2, cost 2, end the run. Even though this seems less efficient, its probably stronger most of the time, because it costs 1 less, and the difference is usually not important.
