Here are my answers (may be right, may be wrong)

1) Currently I don't think we can store cubes outside of events.

2) You can acquire cards by completing missions.

3) PvP to me is just testing out how good your deck is against other people. But again, it all lies on how lucky you are getting those crits/triple attacks.

4) Completing all missions 100% to get energon level to 136. After that you can just continue doing missions for cards to upgrade other cards. Or you can just wait for the next event.
