What weapons to equip Ace Braver with?

I currently have a Ace Braver on Cosmic Break but don't know what to give it, it can kill artillery with it's fists and it has two handy bazookas which can obliterate airs. It is quick and small enough to evade lands but still on certain maps can't pay it's cost back. If there is a non rt weapon  that can increase the effectiveness of Ace Braver or lower the cost (without lowering power and damage) then I would appreciate it if you told me. My in-game name is "Problem?" and play on the EN server.
