@65.246.63.68: With less than 10 cubes left, wait for the X1 or X2 boss, those gives out 30-40 Gold metal ... which you can get some stronger R3 cards (Aim for Prime, Grimlock, Starscream). This will build your strength a bit more.

Also try to learn to snipe with the recharge cubes so you can increase the # of cube you have. Sniping is using one cube to finish off an existing boss ; if you use the recharge cubes for the kill, then you gain 1 cube in your inventory for the finisher.

Since the bosses with higher point appears after the 3rd or 4th day of the event, so f or the next event, try to save up cube for the last 3 days. Most top 1500 player use 40-100 cubes  (if not more)  on the last day.
