Summary
-----------
Ok, i think the deck is too big and needs to be thinned out (51 cards). Before you suggest cards, i have no cards at my disposable like cyber dragon, monarchs.

I found my Dark Necrofear's had a weakness, that when in attack, my opponent would attack, giving me his monster, then using mst or heavy storm. Thats why i have 3 magic jammers.

Thanks in advance
