Good aim will take you a long way on this champion. Learn his range. Always have an escape plan. Understand how to win every matchup (will come with time). Use your mobility!
dont try to hard to chase the Evie unless sh's very low and you have Kill to heal on. most of the time she'll lead you into her team when she runs away. when in a 1v1 gain height on her and force her ice block.
When Sha Lin plants down, reflecting becomes very easy so sha lins will have to take you out with their primary fire. Stay in the air against sha lin as he is a projectile hero also because he can stun you if you're on the ground.
Tyra is very strong against you, in order to win this fight you'd either have to hit a head shot, hope that her aim is off or flank her with the best option being to flank her.
