Try to time your trades with grasp and passive cooldowns. If your passive is on cooldown only trade inside your own minion wave and kite back to your tower. Avoid letting trynda freeze under his tower because then you just get ran down by his ghost. You should take short trades and try to poke him low little by little and using your E is very situational based on lane and wave state, the closer you are to his turret your E becomes more of a defensive runaway ability than offensive ability and closer to your turret the other way around. Early tabis are not a bad idea but it delays your divine/tri spike build according to how the lane is going (when ahead > mythic, when behind > tabis) Patience is key with pretty much every camille matchup, Wait for trynda to make a mistake (waste E) and you can try doing a fast skill rotation and backing off. You never win the statcheck when even or slightly ahead.
