when recently studing my spare cards i came across one i haven't used in a long time, DNA Surgery. When i looked at it reminded me of all the times when i used to use it with Insect Barrier. I don't know why but i decided to look into putting it into my deck. I think i wanted a new theme. So i looked at my deck, and i think i may have discovered a stratigy...

The Stratigy for this deck is a beatdown mixed with cool combos. For example, DNA surgery with Dark Ruler equals a field that can destory flip effects! Think about the posabilities Dark Ruler, BLack Luster Sodier and DNA Surgery! Pretty Beastely huh! I have Solums Wishes in there due to the fact that with Magical Scientist and such i loose a lot of lifepoints. I have Mirror Wall in there because if you notice a lot of my monsters are pretty weak like the Marauding Captains. So it protects me better. Please Rate/Fix this deck, i will return the favor!

-1 Dark Ruler
-1 Slate Warrior
-1 Solemn Wishes
-1 DNA Surgery (you were only gonna use it with Dark Ruler anyways... =\)
-1 Windstorm
-1 Mirror Wall

+1 Kycoo the Ghost Destroyer
+1 Blade Knight/Airknight
+2 Bottomless Trap Hole
+2 Smashing Ground

You were pretty close; it's just that the traps really bothered me. DNA Surgery...just doesn't have synergy with anything in the deck other than Ha Des and Marauding, and even that isn't always gonna be helpful. Solemn Wishes? Gaining life points may seem necessary, but if you use more strategically-based cards, you'll find that you won't need life-gain. BTH is generally more effective than Mirror Wall and Windstorm. Try to add in cards that do more, and that do it better. Also side-deck some Sakuretsu Armors in case you head up against smaller mons like Dons, Captains, and burner decks. 8.5/10.

"Creation Force" could use a fix. Check the sig.

At this time, I can't really think of anything to replace. But the one thing I can say for now is by all means keep the Solemn Wishes no matter what anyone says.

BTW, is that Black Luster Soldier the Envoy version, or the Ritual version?
