Irelia is good champ and good laner actually, she can beat almost everyone on 2-3 lvls, just u need to know how to play. If u want to master her thats very hard to be honest
Irelia is strong against champions who rely on skillshots or melee engagements, as her mobility and crowd control can give her an advantage. She's particularly effective against squishy champions without much sustain. Some examples of champions she's good against include Yasuo, Zed, Akali, and Lux. However, matchups can also depend on player skill and specific game situations.
