how good is corki right now?

He is good, though a little underplayed atleast in my elo. He is pretty unique magic damage attack damage carry (should I call it MDC or ADC idk).

pretty good, adds a good mix of damage to a team and relatively safe pick. Tons of burst damage if you can land all of your abilities.

Side note: I don't think you should base your champion purchases on whether a champion is strong at a given moment in time (unless they're horribly unplayable). Just play champions you like; a champion you like and play well is better than a champion who's "in the meta" any day.

That being said, Corki's solid right now, I still enjoy playing him, though the package is a bit awkward imo.

He's one of the best reworks in the ADC update. Fun to play, has his own niche and is pretty good where he should be. He excels when games are short and has more map pressure than most ADCs. Statistically, he does a lot worse late game (champion.gg) but a good Corki can snowball hard.
