This was my deck before I moved onto Twilight. The deck decimates decks that are too slow to keep up with it and forces faster decks to slow down. You basically abuse the zombie engine for recursing +1's while your opponent struggles to keep up with you in card advantage. The monarchs become instant field presence with -1 for your opponent if they dont have a response to the monarchs effect. The Destiny Draw Engine allows you to swift through your deck while putting threats onto the table with the monarchs and zombies. With three Raizas and 2 Phoenix Wing Wind Blasts main decked it becomes easy to lock your opponents draws while you dump cards like Destiny Hero-Malicious, Mezuki, and Plaguespreader Zombie. The best opening this deck has is having a set goblin zombie and a set wing blast with a monarch in hand. You let your opponent destroy your goblin zombie and you search for mezuki. When they set a card to the backfield you wing blast it at the endphase dropping mezuki to the grave. On your turn you remove the mezuki to special summon goblin zombie and you tribute it for a monarch hopefully Raiza. Then you search your deck again with goblin Zombie and if you have another wing blast then the game should swing in your favor.
