  1. 0–5sBoth side lanes step in; the carrier stays behind the mid wall.
  2. 5–10sTake mid bushes first, then let the carrier collect.
  3. 10–15sPush the enemy side bush so the mine stays yours.
  4. 15–20sAt a lead, spread out and make them come to you.

Comeback: Kill the carrier, then collect as one group — do not trickle back one by one.
