Let's fix this up a bit.
First! Let's get this to be a proper decklist. More Tuners, less Tuners that suck. Psychic Commander fails without Emergency Teleport. Imperial Iron Wall fails at life in the main deck, because I see no Quillbolt loops happening here or anything. 2 Cyber Dragon is standard, not 1, and Big Piece Golem and the Tricky are both failures of cards. The extra deck needs to be bigger.
Reinforcement of the Army is Limited.

~ Deck Strategy ~
While not a hugely solid deck, this deck should be good enough for casual play. Assault Beast grabs Assault Mode Activate, the numerous Tuners tune for random things in the extra deck, the Zombie engine and two copies of Caius are included for extra power - the Cats help search for whatever Trap card you need at the moment, say, a Dark Bribe or a Divine Wrath. Dark Armed Dragon is for backup, and Plaguespreader is too good not to put in.
The spell selection is fairly standard, E-Tele fueling an engine whereby Krebons or Psychic Commander is summoned and the rest easy choices because of the decktype.
The trap selection is a little trickier. Starlight Road is a good negation card in general against the likes of Icarus Attack, Lightning Vortex, or Heavy Storm, and Malevolent Catastrophe alongside it ensures you have a way of getting out Stardust Dragon without resorting to Synchro Summoning. The rest of the line-up are fairly common, the Counter Traps aiding Stardust Dragon/Assault Mode in nullifying threats such as Divine Wrath and Black Horn of Heaven.
