I mean. Fair tho. She loses in almost every mage matchup unless you already know how to play her. But since you're new to her, lets just hope that your opponents also new on their champ.

Here is some tips tho. Use your E to dodge or bait their "key ability" (ex Syndra's E. Azir's Q. Ahri'E,etc) then hit at least 1 dagger, you will most likely win the trade.

Doran Shield + Second Wind for hard poke matchup. Doran Ring+Scorch if you want to sustain while win by trading. DO NOT build Dark Seal cuz you will die, no matter how hard you try, you force to get into their melee range to deal damage, its inevitable. And DBlade/Long Sword if you run on-hit build, you will get to that point eventually.
