In this map try avoid building collectors and relays.
Do not try to destroy digitalis, it grows back instantly
Fight with mortars and use reactors for energy
After you are ready to attack, move one CN to digitalis next to emitter
Connect one collector/relay to one mortar so that mortar is outside of digitalis and collector/relay is connected to attack CN
There is many ways to nullify emitter, use terps if you want easy way
Spoiler
Before unpausing map at start, you can destroy first collector if that helps for you
