Sivir

Where it thrives (5-comp fit)

• Attackworkable · 40%
• Protectworkable · 30%
• Siegeworkable · 30%
• Sivir can hold up an Attack plan — it chains the fight with lockdown once contact is made — but a Attack-first shell gets more out of it (Attack 4/10 vs Attack 4/10).

Kit quirks

• E (Spell Shield) fully negates one incoming spell/effect and heals her 60-80% AD + 50% AP on a successful block, making her one of the few ADCs with self-sustain and hard engage-negation
• R grants team-wide movement speed and CDR-on-hit for her, functioning as a teamfight/objective-push enabler rather than personal burst
• W's bounce mechanic makes her attacks hit up to 8 targets, giving her uniquely strong teamfight and wave/objective clear for an ADC

Dragons & win rate

Win rate when Sivir's team secured at least one of each drake, next to the all-champion rate in that same state. Teams that take dragons are usually already ahead, so every champ wins more with them — the honest read is the gap, i.e. whether Sivir beats the average team that also has the drake. Single-drake samples are thin; treat small counts as suggestive.
