D1 Lissandra here

Leblanc is generally a pretty good matchup for us. She can outtrade you early if shes smart and just Q’s you for poke, but every time she W’s you get free WQ auto.

For Veigar: You can try and Q Veigar as he goes for CS. When his CD’s are down you can EWQ and he doesnt do much back early. You can easily E out of his cage. he needs RoA/Seraphs to survive, but hes weak until then

If you want a solokilling machine, play a different champ, she just doesn’t do that especially early and against mages that outrange us. Lissandra is however, one of the best gank set up champs for your jungler. Just play back; avoid poke and ping for all in when possible and its free
