Favour timeline — the windows in Sejuani's game plan

Read from Sejuani's seat: which stage windows this plan plays for against Tryndamere.

StageFavouredWhy
Level 1TryndamereTryndamere starts fights with Fury from passive crits and his Q damage is already threatening — you have no reliable engage and no CC to interrupt his first trade pattern.
Level 2TryndamereSpinning Slash lets him close instantly when your Q is unavailable, so you lose any attempt to Q-engage; farm safely under your Winter's Wrath range.
Level 3TryndamereHis full kit is online and he wins the Q-W-E Frost chain trade because Spinning Slash threads through your knockup and crits convert the damage lead.
Levels 4-5TryndamereNo power spike for you at 4-5 while his crits climb; Mocking Shout saps your attack damage, but its slow cannot touch Frost Armor — never turn your back, and keep the wave frozen.
Level 6SejuaniGlacial Prison is a 1300-range projectile against Spinning Slash's 650 — it stuns him before Undying Rage can be cast at all, and it is the first moment you dictate the fight.
First itemSejuaniSunfire Aegis raises your contact damage and HP buffer past the point his spin-kite pattern can chunk you, and Undying Rage is 120 seconds at rank 1, a window you count and punish.
Two+ itemsEven / skillBoth of you have late-game tools — your CC chain decides teamfights, but his Undying Rage means any 1v1 execution attempt without team follow-up is a coin flip.

How to beat Tryndamere as Sejuani: the early game

He owns levels 1 through 5 and there is no path around it — his Spinning Slash closes any gap instantly, his passive Fury stacks give every crit trade more damage than your Frost chain can answer, and he can simply use Spinning Slash to walk away if the trade turns bad. Do not try to Q into him; he will spin through the knockup window and start a crit trade you will lose. Farm with the tip of your W range, let him push, and absorb poke with Second Wind. The only Frost-chain trade worth taking before level 3 is if he wastes Spinning Slash on the wave and you can walk up, auto-auto-W-E with full stacks, then Q out before he re-engages.
