Talk:Card Building/@comment-24.57.206.178-20130818002829

This is completely retarded question, but i am new to the game just today. What do the + symbols mean, is it recommended to evolve the same card four times more than once? Will this layer on and become one card or does it stay as two seperate cards and ishould just be using the extras of each same card as enhancement fodder? In other words i read the game faq and the comments below and im just confused :(
