I'd take out both T.G. Warwolf, possibly the Thunder King Rai-Oh (only for all of the searching between Tenki and Factory, which is essential), and replace the Fiendish Chains with Breakthrough Skills. For the monsters, although I may sound like a noob for saying this, I'd take the 3 open slots you have now and throw in 3 Wind-up Honeybee. The Fiendish I only take out because it can be MST'd easily + Breakthrough can be activated on field or in grave. If you don't like the Honeybee idea and feel like Rai-Oh really doesn't weigh down the deck that much, I'd keep it and then just find two of another monster to throw in. Perhaps another Bear and Wind-Up Soldier/Warrior.
