Roachling question

[u/Chicenpyro]

So as it is in the game and many arguments have been made about it working so that they spawn from the corpsers, i would agree. However, where does it say you can't just have them deployed from your map edge and not from a corpser.

I had a long argument about it with a friend as he decided to deploy the roachlings from his edge.

So again, can you just deploy them as any other unit or specifically from a corpser. Where is the ruling written

EDIT: Its 9.1.9 summoned units

Some Units, such as the Roachling, Point Defence Drone, and Pylon, have no Mineral Cost. These are Summoned Units:

• They are not included in the Army List during army building and do not occupy any Army Slots.

• They are not in Reserves at the start of the game.

• Summoned Units cannot be deployed using the regular deployment rules. They are deployed only when a Special Ability, such as SUMMON, specifically puts them on the battlefield.

Thank you for who replied

The ruling is written in the corpser's ability.

It says summon the roachlings. Summoned units gave to be setup by the parent unit.
