Sports Zombie Deck Build (With explanations) (Lower level build)

Baseball zombie is a noob card, period, and should be replaced ASAP.  It doesn't matter that it is a sports card, because the stats are so bad it will easily be dealt with before it can grow into anything.  Basically, any 1/1 card is a noob card because playing them on turn one is horribly counter productive.  You want to get hit by 1 damage - it is affirmatively helpful - and baseball zombie is so harmless can just let him wail on you for a while. 

The problem with this deck is that it is built based on what random low level person happens to have, with no discussion of what to replace.  For example, 4x Arm Wrestlers if you have them is obvious and not debatable.  That is an uncommon, the OP likely only has 2, that is fine, but to just say 2 and not note that you want 4 is not helpful.
