Katarina, Assassin / Mage
Katarina, the Sinister Blade, is an Assassin and Mage champion in League of Legends. Everything below comes from Riot's Data Dragon for patch 16.21.1: ability text, base stats and Riot's tips. Counters and matchups by class are worked out from that text, and each one shows its reason.
Playing as Katarina
Riot's own tips
Picking up Daggers will significantly reduce Shunpo's cooldown.
Try waiting until the other team is distracted with fighting your team, and use Shunpo to teleport into the fray and unleash a devastating Death Lotus.
Using Shunpo on an allied Champion, Dagger, or minion can be a great escape tactic.
Playing against Katarina
Riot's own tips
Katarina's abilities deal magic damage, so even if she's building Attack Damage items, get magic resistance to counter her.
Try to save a disable for when Katarina uses her Death Lotus.
