Skarner should leverage terrain control and suppression to secure objective fights and punish Trundle's lower mobility outside his (W) zone.
Prioritize controlling river chokepoints to limit Trundle's strong dueling and invade potential early game.
This matchup revolves around managing objective control and using wall-based ganks to isolate priority targets before Trundle can force extended duels.
Jungle Plan
Prioritize pathing through wall-heavy gank lanes to maximize (E) pin and (R) suppression impact on isolated targets.
Contest river vision and hold terrain control before dragon and Rift Herald to deny Trundle's early objective setups.
Use lane priority to create safe counter-jungle windows and force Trundle into unfavorable fights away from his (W) healing zone.
Danger windows
Avoid isolated river fights early where Trundle can use (E) pillar to trap or slow you.
Be cautious contesting objectives when Trundle has lane priority and (R) available, as he can drain your resistances.
Low-health clears or forced smite fights near walls are risky since Trundle can stat check and out-sustain you in duels.
Early game
Start pathing camps toward lanes with reliable wall angles to maximize (E) gank threat early.
Fight for first Scuttle only if nearby lanes have priority to support river control and avoid Trundle's strong early dueling.
Avoid extended early invades against Trundle unless you have vision and lane priority, as he resists invades well with stat steals and sustain.
Power spikes
Level 6 is a major spike; use (R) suppression to isolate and suppress Trundle before he can use (R) stat drain.
Skarner's frontline tankiness and suppression scale well into late game, increasing value in grouped fights.
Trundle's first dueling item powers his extended fights; Skarner should force fights before Trundle reaches this to avoid prolonged stat checks.
Win conditions
Convert wall-based ganks into secured dragon and Rift Herald control by leveraging suppression and terrain control.
Use vision and lane priority to force Trundle into isolated fights where your CC and tankiness outvalue his sustain.
Scale into late game to maximize your frontline control and suppression in teamfights, denying Trundle's splitpush impact and extended dueling strength.
