How to play it
DO
Watch R -> Flash
His R plus Flash is his only gap-closer onto you — stay out of that range when it's up.
Trade on his CDs
Force trades while his Q and E are down — all your abilities outrange his only CS tools.
Bait then poison
With mana and both poisons, throw one, then land the second after he ults in.
DON'T
Never sit in his E range while soaking minion aggro — the slow stops you disengaging unless Stormraider's Surge procs.
