Very nice deck:

- Ultimate Obedient Fiend
+ Cyber Dragon

- 2 Reload
+ 2 Book of Moon

- Banner of Courage
- Ultimate Offerings
+ 2 Riryoku

Very well put out together.............. 8.9/10

My question, what will be the backup if Skill Drain doesn't come through (ie: it gets destroyed, bad draws while Skill Drain is still in the deck, etc). But the same can be said for other card dependent decks like Gravekeepers, and they do well also, so that's just an inherent weakness I guess.

-Rush Recklessly (monsters already have high ATK)
-Banner of Courage
-Ultimate Obedient Fiend

+Exiled Force
+Big Bang Shot x2 (opponents' monsters will be in defense alot)

Otherwise, 9/10. Decent build (though I don't like the overwhelming dependency on one card decks.)
