Forum:In-n-Out Shadows Deck

Greetings everyone, Manitsque here. I'm working on a DARK Deck. the type of deck I'm building focuses on the graveyard and removing-from-play. It's playability level that I've given it is about a 5/10. You guys can give your opinions too. But, what I really want are tips on how to make this deck better. I was thinking on incorporating Synchros, but I can't seem to find a way how to. Yeah, and my Side Deck needs work too. Thank you =)

Side Deck:
 * Evil Hero Infernal Gainer x2
 * Dark Hunter x2
 * Dark Nephthys x1
 * Earthbound Immortal Ccapac Apu x1
 * Mystic Plasma Zone x2
 * Archfiend Soldier x3
 * Light-Imprisoning Mirror x2
 * Hate Buster x2
