Ive never gotten a super rare from spending $$ (just episode Hound/Dirge). And I have Prime, Flamewar (non-episode version), Prowl and episode Jazz.

It takes times and youll do a few events before your at a comfortable spot. Work on fully leveling, trans-scan and leveling your rares. When no event is taking place, work up your credits. Sell commons and feed uncommons to rares. When an event starts, drop a buck on an episode rare and use your cache of uncommons to level it quickly. Wash, rinse, repeat.

Eventually youll get a deck capable of dropping early Raid bosses easier. That'll net you a bunch of extra cubes (just make sure you get more back then you spend). Without paying too much attention to it I stay at around 100 cubes and have about 60 energon refills. Mid-tier bosses are a bit tougher and get you those energon refills. Save all your resources for the last boss and then go nuts. Search for and find as many as you can. If you know theres no way youll get mvp then there is no use in using more then 1 cube on them. Then hope others will help you.

Floating around rank 5k right now, using only cubes as needed.
