Welcome to the game.

The best way to build up battle cubes is to accept your first free ones, then use them to leverage for more. It's important to build up a strong deck, in order to be able to maximize your damage to the first bosses. They will pay out 2 battle cubes, and if you are able to kill them with 1, then you are gaining 1 cube per boss kill.

At first, this will be difficult. I recommend slowly playing these events, and not spending your cubes, other than the ones that are produced naturally. This will allow you to build up more for future events.

Once your deck power improves enough, you can start expecting to "one-cube" bosses. The very first low level ones will require a deck power of about 4,000 or so. In order to kill the second tier level 5 bosses (Arcee, in this event's case), you will need to have a deck power of over 10,000. This will normally involve either using some Mobacoins to get some event bonus cards (3X /  5X) or just building up a strong deck with stronger R4s.
