Why LeBlanc is favored
LeBlanc can pressure Veigar before his passive stacks up, and her mobility lets her turn that lane pressure into roams and ganks that he struggles to follow. The advantage is strongest early; Veigar can outscale if LeBlanc lets him farm safely.
How to play as Veigar
Save Event Horizon for LeBlanc's Distortion commit; if she starts a trade before you place the cage, use its edge to stop her from escaping through the perimeter.
Event Horizon is Veigar's main way to stop LeBlanc's Distortion engage; its edge stuns her if she crosses through it.
Veigar gains permanent Ability Power from hitting champions with spells and from takedowns, while last-hitting with Baleful Strike also adds stacks, so uncontested farming increases his later threat.
How to play as LeBlanc
Stand beside the minion wave so Veigar has to choose between poking you with Q and farming with it; use the space to take short trades, then back off before an active cage traps you.
Use Distortion for a quick trade and return rather than staying for a full rotation; if Veigar places Event Horizon before you go in, wait for the cage to end instead of crossing its edge.
