Opener

Play slow for one cycle: confirm trap behavior and mark unsafe lanes.
Set up a responder to rescue trapped units.

Midfight

Force him to choose between shooting and trap placement; punish when he spends bonus turns on traps.
Rotate through safe tiles; don’t path through freshly contested ground.

Finisher

Commit burst once trap density is controlled or you have a clean safe lane.
Don’t chase into unknown tiles on the last turns—trap wipes happen at the end.

Positioning, run killers, and loadout reminders.

▾

Run killers

Walking through lanes without trap discipline: invisible traps steal turns and positioning.
Chasing into adjacency: he punishes adjacent hitters with pushback, breaking your tempo.
Misunderstanding minimum range: standing at 2 tiles can be the safest spot; standing at 3–5 invites shots.

Positioning rules

Treat any open lane as trapped after his bonus turns—don’t full-commit blind.
If you must approach, do it with a ‘sweeper’ unit first, not your carry.
When possible, hold positions within his minimum range band to deny the ranged basic.
Avoid trading adjacent hits unless you can handle the pushback consequence.

Loadout hints
