Metal Slug Defense Wiki

So,I started playing this game again (it's the fifth time) and I want to play it fair, with no time cheating. So I was wondering, can anyone give me some help for my deck?

It needs to be very cheap, but also very strong in Wifi. I want it to be very easy to use with fairly low AP so I can deplow them quickly. And maybe one or two KoF units.

Please answer guys, I don't want to buy some crap units with all my medals... Started the game today, and I currently have 30 medals. I really need some help, so please answer.
