LeBlanc is a mobile AP assassin aiming to snowball through burst trades and roams against Garen's medium lane pressure and durability.
Manage lane priority to deny Garen free farm and avoid giving him passive health regen windows to threaten execute range.
Trading pattern
Use (W) to engage burst combos and reposition, then threaten (E) root if Garen cannot disengage.
Punish (Q) cooldown by stepping forward for trades when his silence is down.
Avoid using (W) aggressively without a clear escape path, as missing it leaves you vulnerable to Garen's all-in.
Danger windows
Respect (Q) silence and (E) spin damage combo, especially when (Q) is up, as it can interrupt your engage and punish missed (W).
Avoid extended trades where Garen's passive health regen and (W) damage reduction outlast your burst.
Post-level 6, be wary of (R) execute range after you take chip damage; back off if low health and no immediate escape.
Early game
Use level 2 burst with (Q) plus (W) or (E) to punish Garen's short trade attempts before he can silence or spin.
Avoid extended trades where Garen's passive and (E) spin damage outlast your burst.
Hold the wave near your side to prevent Garen from stepping up for short trades and to keep roam windows open.
Power spikes
Level 2 unlock gives LeBlanc a strong burst combo to force trades or all-ins; use it when minion and cooldown conditions favor you.
Level 6 (R) enables picks and roams; track its availability to commit only on confirmed all-ins or to escape.
After your first completed AP burst item, increase pressure on trades and wave control, but respect Garen's bruiser item spike that boosts his durability.
Win conditions
Snowball lane by punishing (Q) cooldown and spacing mistakes with your level 2 burst combo.
Use your high mobility and (R) to create picks, secure kills, and roam to side lanes to extend pressure.
Deny Garen free farm by crashing waves before he can safely trade, forcing him under tower where your poke is safer and his engage is limited.
