Favour timeline — who owns each window

StageFavouredWhy
Level 1TryndamereHe just walks up and right-clicks you off the wave — at level 1 you have one ability, no poison to stack, and no kill threat back.
Level 2Even / skillOnce you have two of Q/E you can prime-and-Twin-Fang for a real trade, but his crit spin still bursts hard — neither side clearly owns it yet.
Level 3CassiopeiaFull Q-to-E poison chain plus the Miasma ground comes online — lock his Spinning Slash in place and chain Twin Fangs through an extended trade he can't win.
Levels 4-5CassiopeiaRanks in Q and E let you chain near-continuous Twin Fangs; ground his gap-close with Miasma and you out-DPS his spin every trade.
Level 6Even / skillPetrifying Gaze stuns his all-in, but Undying Rage holds him at 1 HP for 5s — you win the trade and kite, but rarely get the clean kill.
First itemCassiopeiaYour early-item poke plus Serpentine Grace move speed kite a pre-crit Trynd out of lane — force trades while Miasma still answers his E.
Two+ itemsTryndamereIE and lifesteal crit out-sustain and out-DPS your single-target Twin Fang, and Undying Rage ignores your burst — a scaled Trynd reclaims the lane.

Early game (levels 1–5)

Level 1 is his — he just walks up and right-clicks you off the wave while you have one ability and no poison to punish back, so concede the CS and don't throw a lone Q. The lane turns once you have two of Q/E: prime with Noxious Blast, then Twin Fang the poisoned target for a real trade his early spin can't match. The key tool is Miasma — save your W ground for the instant he Spinning-Slashes in, because a grounded Tryndamere can't dash back out and just eats your ramping Twin Fang.
