the biggest thing about the events is the fact that you can upgrade your cards faster. Play a lot of the missions. When you find an episode boss, if you have a free battle cube waiting, use it to start a battle-this will get you a free energon cube everytime the battle is finished for you. If you don't have any free battle cubes, just hit the back button in the top left and ignore it. After you have 6 just sitting there, you will not get any more episode bosses and will only get mission cards. If cyclonus cards will show up in your deck, do those missions to try and get them, that will help your deck. otherwise, I think the best mission to do is the decepticon find the communications terminal (top decepticon, left decepticon, mission 3). Those cards are all good for upgrading.

Another thing you can do is when you have free battle cubes, when the bosses get bigger, just join in battles when they get under 40%, meet the participation minimum, and have a lot of time left. these almost always get finished, and while you won't get any cubes for it, you will get a lot of cards. Make sure you select wisely, as a lot of the big bosses don't get finished off, and it wastes cubes.
