Akshan

Akshan completely counters Panth. I always ban him.

Vex

Not quite as scary as Akshan, but Vex is still a tricky one. As long as you don't let her kill you you'll be fine. Stay safe and stay back when she has full stacks

Zoe

Zoe is another exception to the mage rule. She does loads of damage if she lands her sleep but as long as you dodge it you should have the game in the bag.

Vladimir

Rush oblivion orb. AP Panth doesn't do well in extended fights, his damage comes from burst. Vladimir is annoying but not impossible.

Malzahar

The only problem with Malzahar is his shield. If you can start Q, make sure he doesn't have his shield, and then all in level 2, you should get a strong early lead.

Anivia

Anivia's massive stun and her passive are quite annoying but earl game you do way too much damage. If you can kill her early you're set. Start W and keep up the pressure.

Heimerdinger

Heimerdinger is annoying, but as long as you stay safe and only go in when you know you'll win, you should be fine. His lane pressure is annoying but don't take stupid trades and he shouldn't be able to do much.

Yasuo

Yasuo should be easy, don't get hit by tornado and keep his shield down at all times.

Yone

Yone is also easy, keep up the pressure and poke him out every time he tries to stack his Q on the wave.
