Obviously a 2-1-2 line is far superior (and a 3-2-3 over that, ect., dending on how important it is to the deck). There are other cards with the other ones power for next format so that you don't have to use him if you only have 1 copy of him (would trade for more if you really want to play him though). But if youre using him for his power, you would only want a 1-1(or 0)-1 line of him because having an extra mudkip/marshtomp probly won't help you that much.
