Control the mine in the middle and hold the gems together: the carrier is the fight, not the gem.
Left laneBo — zone: deny the bush and the choke
MidRico — skirmish: trade hits and finish the low target
Right laneEdgar — dive: wait for the cooldown, then take the back line

0–5sBoth side lanes step in; the carrier stays behind the mid wall.
5–10sTake mid bushes first, then let the carrier collect.
10–15sPush the enemy side bush so the mine stays yours.

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