So I've recently heard about a fun little grinding trick for power ups. Tested it out, and it totally works.

Go into endless. Assuming you get a free power up as one of the cards, select it. When you go into the plant selection screen, do not select any plants. Force close pvz2 (For iOS devices, it seems like you can just quickly double tap the home button, go over to pvz2, and slide it away. This forces it to close.) and then reopen it. Go back to the endless zone and then you can repick your cards. Just pick up the power up, and then rinse and repeat. It seems like this only works about 3 times before entering the endless zone just automatically brings you to the plant selection screen, but it works well for grinding power ups. Not 100% sure if this lets you get both a power up and say, a Snap Dragon in one 'pick. Could try it later, though.
