This deck is based on doing your P.U.N.K combo and the doing yout Zombie combo. The additional P.U.N.K cards are their to get you of sticky situations or if you started with a bad ahnd so you can start your P.U.N.K combo.
You dont need to use a side deck, but if you do put Anti Spell Fagrance and/or Lava Golem or Gamasiel the Sea Kaiju
If you have the money, I would recomend putting in the adventure engine by taking out some P.U.NK cards and removing Amazing Dragon with Hot Red Dragon Archfiend Abyss
