I'm pretty sure Set 3 and Set 4 are the same "set". Set 1 is made up of "Gold" and "Silver" altogether. People are looking into the "set" thing too much.

Anyways I think I understand springboards. You play Springboards on a lane. When you play a Plant there, the Plant is bounced back to your hand with its new upgrade as given by the springboard.
