For this event the x5 is super powerful, the same level as elite one and better than twinstrike after event.

Raid cards are the best way than buying blue cubes.

I saved 160 blue cubes since last night

I would agree with this post, you can pick up a (x3) R4 Cyclonus robot/alt mode for only 400 coins. Its a great way to build up your deck if your just starting out, and make sure you MTM to get the max value out of these cards.
