Level 2SennaYou win level 2 because hitting 2 first lets you punish a support who can only heal reactively.
Level 3SennaYou win level 3 as your poke keeps outpacing his early sustain before shields scale.
Levels 4-5Even / skillLevels 4-5 are even as his W shields and Q slow start absorbing your single pokes.
Level 6Even / skillLevel 6 is even because his R cleanse-heal negates your all-in but he still threatens nothing on you.
First itemEven / skillFirst item is even as his sustain roughly matches your poke output.
Two+ itemsSennaYou win 2+ items because stacked souls and long-range Q/R let you pick past his shielding.
