Forgotten Title of mobile games

It's a turn based, 2 dimensional duel where we have a robot, and we start summoning some kind of drones to attack the enemy robot and vice versa, and certain combination of drones can produce different effect. (shield, extra damage, a mega laser that deals tons of damages)

that's all i remember
please help

 

@javaniy Sounds a bit like Super Mechs, though I've forgotten about the "combination of drones" part (whether it exist or not).

There is combination of parts if that's what you mean instead. And they do the things you've said.

 

It's not super mechs, and if I remember correctly, the graphics is mostly black and white

 

I played a game exactly like you described on a BlackBerry PlayBook xD
Super old, dunno if you can download it anywhere else, and might not be the one you’re looking for: https://appworld.blackberry.com/webstore/content/113902/?lang=en&countrycode=US
