If you are even, you have a small chance killing him at lvl 6 if you have the level prior. Once he is 6 with above 70 IQ, you will never win until the defeat screen, he will just E your Q2 and stat check you every single time. You are basically an insect in this matchup, with Jax nibbling you to death. An other option you have is standing in the middle of the lane, and sometimes bad Jacques will Q-E into you, if that's the case just tank his damage then buffer you E onto a wall, you will get stunned but you have enough time to E onto him again, if you hit him and you have your shield you can take the trade, but don't overextend if he's like mid HP or more.

Level 2 you take E since he will take his Q, and you must stick to a wall everytime and continue spamming your W on him he will Q then E into you and then you can do a quick E to stun him and get out. Level 1 you start W as you can't autoattack him (lol). The only hope you have before he becomes a huge stat stick champion is early game if he doesn't play very well. He wins early game, he wins mid game and he wins late game. Gazibulle says “The hardest Camille matchup, should be a permaban every single game if you plan on playing Camille. You just Q, E, Stridebreaker and run away before he can do anything to you.” Once you have Stridebreaker, you can start trades with Q because it still counts towards Phase Rush. Your Ult goes through his Ult resistances so it's pretty straight forward.

If you wait for him to waste his Ult passive, it's even more favorable for you. Once you are both level 6, you win trades as long as he doesn't have his passive stacked. If you use it too early and he holds the recast, you lose the trade hard. Wait just a tiny bit after he can recast with E and then use your W.

He has 1 second to use his stun and your W tenacity lasts. Use your E when he starts his E and block the stun with your W. An easy way to avoid dealing with his passive is to look to fight him when you are slow pushing the wave and avoid trading when he is pushing into you. Avoid trades early, especially if he has more than 2 stacks on his passive. Any competent Jax will respond with E as soon as they see you start the leap. It's not a "mind game", you just are being lazy. Do NOT ego Q into him while his E is not on cooldown. Aberrant Demon says “Your E range is 25 higher than Jax's E range but that doesn't really matter because Jax can just take Corrupting Potion and Time Warp Tonic.
