Read from Senna's seat: which stage windows this plan plays for against Kai'Sa.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Senna | Level 1 you out-range her weak early poke and win trades. |
| Level 2 | Senna | Level 2 your W-Q all-in punishes her before Plasma stacks. |
| Level 3 | Senna | Level 3 your range and sustain keep the lane edge yours. |
| Levels 4-5 | Senna | Levels 4-5 root pressure denies the CS she needs to spike. |
| Level 6 | Senna | Level 6 your R duel-shield beats her proc-dependent dash ult. |
| First item | Senna | At one item your minion spacing and W picks blunt her evolve burst. |
| Two+ items | Senna | At two-plus items your global R and pick threat out-fight her before she isolates you. |
Levels 1-2 you out-range and out-trade a scaling Kai'Sa: contest melee minions and W-Q her whenever she steps up to CS before her Plasma stacks matter. Contest the melee minions before her plasma stacking matters, and root her whenever she steps forward to farm. Piercing Darkness pays for the trade twice by healing you as it chips her. Take the souls she cannot contest, since delaying her first evolve is worth more than any single exchange.
