A ten-game plan for Sejuani on a fresh account — the abilities to drill, the real cooldowns to respect, and the habit that costs the most games.
A new account gives you ten normal games before ranked opens. That is the only stretch where you can misplay Sejuani at no cost to your rating, and most players spend it on autopilot.
Sejuani is a tank whose job in a fight is to start the fight on your terms and be the most costly thing to ignore. At 150 attack range Sejuani has to walk into damage to deal it, so every trade begins with a decision about whether you can afford the walk.
Sejuani is mana-gated, which is the real limit on how often you can contest a wave early.

After being out of combat, Sejuani gains Frost Armor which grants Armor and Magic Resist and immunity to slows. Frost Armor persists for a short time after Sejuani takes damage. Sejuani can damage a stunned enemy to shatter it, dealing massive magic damage.
Sejuani charges forward, knocking enemies into the air. The charge stops after hitting an enemy champion.
Sejuani swings her mace twice, dealing damage, slowing enemies and applying Frost stacks.
Sejuani freezes and stuns an enemy champion that has maximum Frost stacks.
Sejuani throws her bola that freezes and stuns the first champion hit and creates an ice storm that slows other enemies.
Take Glacial Prison at levels 6, 11 and 16 — the ultimate is always worth the point it costs.
For the basic abilities, Arctic Assault (Q) gains the most from being ranked: its cooldown falls by 6 seconds between rank 1 and max, which is the largest improvement in the kit. That is the usual argument for maxing it first.
This is reasoning from the cooldown data, not a win-rate ranking — a matchup that punishes you can invert it.
Do not look for kills. Farm, and watch the cooldown figures above — a tank that walks up with its main ability down is giving away a free trade, and at rank one those cooldowns are at their longest.
Melee last-hitting under tower is its own skill, and these are the games to practise it deliberately.
Now use the cooldowns. The recurring error for this class is engaging before anyone can follow up — it never feels like a mistake in the moment, which is exactly why it survives into ranked.

Movement speed 340 and attack range 150 do not grow with levels — they are the two numbers that stay true all game.
