You can usually play her into any jg matchup but she is weaker the more cc the enemy team has making her good against squishy teams with bruisers as the only tanks, but she can be played into tanky teams you just have to make sure that you engage properly with your ultimate and dive the adc or a mage. She doesn't particularly lose any 1v1 in the jg but she can lose late game if you are behind with no tank items for team fighting.
