Forum:DD Deck. Need help to further make it better.

Okay, so my deck is a DD deck based off the Dark Emperor structure deck. The list is as follows:

Monsters (18): DD Warrior Lady x 1 DD Assailant x2 DD Survivor x3 DD Warrior x1 DD Scout Plane x2 Kycoo The Ghost Destroyer x1 Gren Maju Da Eiza x2 Golden Homunculus x1 Banisher of the Light x1 Banisher of the Radiance x1 Des Kangaroo x1 Magician of Faith x1 (Thinking of switching with Fire Princess) Caius The Shadow Monarch x1

Traps (9): Return From The Different Dimmension x1 DD Dynamite x2 Sakuretsu Armor x1 Skull Lair x1 Macro Cosmos x2 Ceasefire x1 Torrential Tribute x1

Spells (14): Giant Trunade x1 Soul Absorption x1 Heavy Storm x1 Swords Of Revealing Light x1 Dark Hole x1 (in tournaments I switch this out for Lightning Vortex) Nobleman of Crossout x2 Enemy Controller x2 Spell Absorption x1 (Thinking of switching to Soul Absorption) Reinforcement Of The Army x1 Mystical Space Typhoon x1 Change Of Heart x1 (Switch with Brain Control for tournaments) Dark Core x1

Total Deck: 41 cards

Now, I need constructive criticism. My budget is limited, but if you know of any cards that would help me greatly please tell me and please just if you have ideas of what to take out, what to switch, and what to add in, please tell. Once I find a Fire Princess, I am switching it with Magician of Faith.
