Marked for death, curse of decay, agony and chains of agony are top picks for me because they work in mirror matches. But chains of agony isnt one i use very much. I keep 1 rust, 1 to 2 chant of rage, and so on. I cant remember all the enchants i use. But puddin is right - every card i just mentioned is a card used for the enemy. The only cards i have to help my zombies are force wave, lesser teleport, gravikor, and zombie frenzy. If im feeling saucy i will add an extinguish just in case. But the fact is you dont need to support them because they are resilient, bloodthirsty, and are very generous in their mana cost. They are self relient creatures that dont need to be taken care of which is why i use them in tournaments. Just throw them out and let them do their thing.
