Maguro Map is a wonderful tool for many things such as training your skills, testing enemy compositions and experimenting on customised units, abilties and effects which I do all the time.
Maguro Map is in Custom map in Arcade (just type MM).
There are 2 special things I found.
1. You can input 2 commands at once.
Maguro put in commands (Fastbuild, Godmode, Decide AI builds) for various circumstances.
You can put in maximum of 2 commands at once.
-God -Fastbuild or -aw -aichoice (happens only at odd time. 1st 3rd 5th etc). Sometimes it works and it doesn’t
Personally, It would be very helpful if I can input 3 or 4 commands at once.
for example: -fastbuild -money -pai -vision
2. Always put Special Unit command at DoN before you play the map
I recently figured this out trying to experiment on Choker Bugs on Dehaka. You can use -Pick X Y command to decide which special Infested comes to your base. Make sure you do this before the map starts.
To Maguro, Thank you very much for making this map. I was able to experiment so much in this map.
