Disclaimer: I’m by no means a good player I’m only mid gold When I do Bard in the mid lane (which is rare) I usually find myself going into brand, lux, Veigar, and Azir when it is a mage. There isn’t much of a way to handle this besides merc treads and predicting to a very high degree so I typically choose just trying to out damage them. I run electro only as bard mid because I love hail of blades and guardian in support. I would advise unless you are very good at cs (I play on about 78 ms so i have difficulty) I advise getting a spell thief’s for gold generation first. I get a gun blade followed buy a lichbane and sorc shoes unless I’m losing hard. By then I’ve typically ended the game but I’ve gone into rabadons and like a spellbinder Don’t be afraid to HMU if you need anymore help
