Deck drops sexy openings like they are going out of style. A face down Snowman Eater or a Diamond Dude is a pro opening. Since very little can take out a Defense Position Snowman Eater it will almost always get the kill while remaining on the field. And will all of my spells being normal Diamond Dude has a great chance to hit.
After that deck can go nuts, if your opponent over extended it is a great time to put out your first AZ and shut that down asap. If they did not, playing it slow with more Diamond Dude action is usually the best call.
Eventually it will come to the point that are you supposed to open up your opponent like a jumbo sized can of tuna and begin to make salad with them. Starting off with a Brionac to get rid of any pesky back field cards, then leading into 2 copies of AZ is a good way to win the game.
Playing this deck is all about being conservative, you need to know without a doubt when it is safe to overextend for your game-winning turn and holding cards like Deep Sea Diva and Brain Control for that time is critical. You should only play AZ when you know it's going to gain you advantage or win you the game, putting him out for extra damage is unacceptable!
OUT!!
(and before anyone asks, yes, the Amphibious Bugroth does have a use. It's for when Diamond Dude whiffs an Instant Fusion and you don't have anything to do with it next turn. Slap down the Bugroth and you have the material you need for AZ. And yes, this deck does play Destiny End Dragoon. Since the pieces are in here I saw no reason not to include a copy, and once it's in play/grave winning just becomes that much easier too)
