Rate/Fix my Fiend.Burn Deck [10points]?

I give it 8 out of 10. Kisetai and Dark Dust Spirit are good cards for doing a lot of damage without getting hurt. If you have any monsters above level 4, I wouldn't use Level Limit-Area B. I have a fiend deck. My favorite combo is goblin king with opti-camouflage armor. As long as you have another fiend on the field, goblin king has at least 1000 attack points, and, thanks to opti-camouflage armor, can attack your opponents' life points directly.
