Shyvana should leverage her very high clear speed to outpace Nasus's slower jungle pathing and secure early tempo advantages.
Prioritize dragon control and objective trades where your sustained damage and form scaling outmatch Nasus's dueling and scaling juggernaut style.
Avoid early river fights without lane priority or fury stacks, as (W) and scaling make isolated skirmishes risky.
Jungle Plan
Use fast camp cycling to maintain tempo and trade camps and objectives rather than forcing early ganks.
Fight for dragon control when bot and mid lanes have priority to leverage your objective control strength.
Avoid direct early invades or river fights unless you have lane priority and fury stacks to mitigate Nasus's dueling threat.
Danger windows
Early isolated river fights without lane priority expose Shyvana to (W) slow and extended fight damage.
Low-health clears or forced smite fights can be dangerous if Nasus arrives first or with lane assistance.
Avoid fighting Nasus post-level 6 and after he has stacked (Q) damage unless you have clear numerical or positional advantages.
Early game
Start with a full clear to hit your dragon-form and item power spikes faster than Nasus.
Contest first Scuttle only if nearby lanes have priority to avoid risky 1v1 fights against Nasus.
Track Nasus's jungle pathing for counter-ganks and avoid early invades before you have fury or lane support.
Power spikes
Level 6 grants Shyvana dragon form, increasing dueling and objective control; use this to pressure dragon and skirmishes.
Nasus's major spike comes at level 6 with his ultimate and when he stacks (Q); respect his extended fight durability and avoid prolonged fights then.
Shyvana's item and form scaling mid-game allow her to dominate teamfights and objective control before Nasus reaches his late-game juggernaut strength.
Win conditions
Convert your faster clear speed and dragon-form power spikes into consistent dragon control and objective trades.
Use vision and lane priority to force Nasus into farming under pressure, denying him safe stacks.
Leverage your mid-game teamfight strength in dragon-form to control fights before Nasus scales into a side-lane threat.
