Droids

[burners]

get 3 or more droids.
Hotbar all 3 next to each other
tap down all 3 keys at once.

The game only rollsback 1 summon, so you'll get 2 out. 1 goes berzerk and runs off, but it comes back. You can do 4 for 3 pets, 5 for 4 pets. 4 binary load lifters look really nice.

It gets really good for bomb pets <3

When 1 is destroyed, the next thats out autoactivates and you can send it straight on its suicide mission
