Grievous Commandos
63 General Grievous, Scourge of the Jedi
24 Commando Droid Captain
51 Commando Droid x3
9 Battle Droid Officer
3 Mouse Droid

Here's a semi-competitive tournament squad I decided to make using the Commando droids since I like them so much.
Pros
-Commandos gain Double Attack added onto their twin from the Captain, and Extra Attack Thanks to Grievous.
-All Droids gain an extra +4 attack from Grievous. The Commandos gain another extra +4 from the Battle Droid Officer.
-The Mouse Droid extends all commander effects.
-Grievous, Scourge of the Jedi, is tough and the Commando Droids are going to be shooting a lot with a potential of doing 120 damage if they pull off a complete triple twin with squad assault.

Cons
-Commando Droid won't survive long if put out into the open. (It'd be nice if they had stealth or mobile attack)
-Low activations. I would have liked to put in San Hill to have some tempo control, but I sacrificed him for more firepower. I also would have liked to put in a Battle Droid Sargent for another +10 damage.
-No door control whatsoever.

So tell me what you guys think. Feel free to comment either here or on the squad page. Ratings are welcomed.
