This deck is so all over the place brotha. Let me look at these bladerz and get back to you.

tell him that he needs to have a grave yard. think about what destinty hero dashers second ettect is (to sommon a monster without tributing).
cards like worrior lady need to be sent to the graveyard, where as lesser fiend gets rid of it all together. telll him to start again

You should really get rid of cards like dark blade,kuriboh and fissure.Replace them with better cards that focus on one theme.This deck's all over the place.
