Shen

Place your Spirit Blade (Q) behind your opponent before trading: passing through it gives you an empowered Q with bonus max HP% damage.

Use your E (Shadow Dash) through minions to taunt the enemy by surprise — this is the main trading combo in lane.

Keep a constant eye on the minimap: your R (Stand United) can turn an allied fight anywhere on the map. Don't use it too late.

Your passive shield (Ki Barrier) recharges faster when you use an ability — trade aggressively when it's available.

In teamfights, taunt the carries with E then use your W zone (Spirit's Refuge) on your own carry to block enemy auto-attacks.

Stay on the same side as his Spirit Blade: if he can't pass through it, his Q deals much less damage.

Punish him when his E (taunt) is on cooldown (18-14s) — it's his only trading and engaging tool.

Watch your allies' HP bars: when a teammate is low, Shen will likely R. Engage him at that moment to cancel it or force a choice.

His W zone (Spirit's Refuge) blocks auto-attacks but not abilities — AP champions or ability-based damage dealers have an advantage.

Warn your teammates as soon as Shen hits level 6, and especially when he disappears from lane — he's probably teleporting to an ally.
