The plus symbol on a card means that it is the result of two of the same cards being evolved together. At the very least, you want to make a 4-1 of any card your get, but that is the weakest possible evolution. check out the links on the pages above for how to evolve the cards (I would recommend doing a 4-3 or better on the cards you are going to use in your deck. Also, the product of any evolution is one card; there will not be two cards left after evolution.
