Forum:Help my Koa'ki Meiru deck

From: 71.245.35.145

I'm back with a new deck, Koa'ki Meirus. It's just the basic strategy, to keep the monsters on the field by sending Iron Core of Koa'ki Meiru to the Graveyard. The deck is still under contruction, but I need more help on what cards to put in. Apart from the Core discarding, weirdly enough, I put Power Tool Dragon and Stygian Sergeants to kinda help my deck so I won't be monsterless. Also, it has cards that protect Koa'ki Meiru monsters from being destroyed by their own effects like Iron Core Armor.
