Starting powerups?

[Bomber Boy]

Hello! How can I upgrade my current starting powerups in ARENA mode? (bomb range, bomb quantity, and speed)

Those power-ups can only be upgraded if you upgrade your experience level, to upgrade your experience level you must earn them in the chests by improving cards, each time you level up you will get more power-ups, the maximum you reach are 4 of each at level 10
