Khaimera is my main, and I have always dominated as him, consistently getting games with 18+ Kills, and 4 or fewer deaths. That was until the match I played just now, where for the first time ever, the other team go to max level and cp before my team won. After that I was USELESS. IT SUCKED. I spent more time dead then alive!
My deck has always been a mix of Attack Speed and Armor (Too little for the current meta I think.) and I suffer from lack of any Rust Breakers. Well, this is it:

Early Game: x1 Health Pot x1 Flashfire Piston (Red Buff)

-Get 3-6 cp then return to base.

Buy Brawlers Key, then upgrade Flashfire piston (x2 Minor Strike, x1 Minor Kinetic).

Then upgrade Brawler's Key with x1 Major Strike, x1 Strike, x1 Minor Strike.

Mid-Late Game: Spiked Bone Plate x2 Guard, x1 Strike Thorned Greenweave x2 Barrier, x1 Strike

Windcarver Blade x2 Major Kinetic, x1 Strike Windcarver Blade x2 Major Strike, x1 Major Kinetic

By this point I would have sold my old Flashfire Piston (x2 Minor Strike, x1 Minor Kinetic) and replaced my Brawler's Key with a: Impact Hammer x1 Major Wound, x1 Wound, x1 Minor Strike

And I'd top off the deck with: Flashfire Piston x2 Major Strike, x1 Kinetic

PLEASE HELP ME. Any suggestions would help, but please remember that I currently have no RustBreakers. HELP.
