Help with Dragon Darkness

you can see my problem...

i love dragon and also darkness.
but combining that two is a bit confusing because i am new in this new brand of yu-gi-oh...the last game i played is YGO-5ds-2011 on DS.

so in my deck, the key card is the "the dark creator" and "REDMD"...since "The dark creator" is lvl 8- i put "trade-in". I also put "lightpulsar dragon" because it will help me to get back my destroyed REDMD. another card is dragon type darkness type, "darkflare dragon" = to send dragon in my hand and my deck, "dark horus" = for trade-in, "galaxy-eyes photon dragon" = for trade-in and help lightpulsar dragon.
another monster card is "sangan, and tour guide" = for xyz then increase number of dark monster in my grave.

now the question is...this deck is really unstabble, sometime when i have luck i can defeat my opponent, but sometime i also get OTK because i can't get any monster to be summoned...
my deck
monster : (20)
- REDMD x 3
- The Dark Creator x 3
- Galaxy-eyes photon dragon x 2
- Dark horus x 2
- Lightpulsar dragon x 2
- Darkflare Dragon x 2

- Sangan x 1
- Herald of creation x 2

Spell:(12)
-Trade-in x 3
- Dragon ravine x 2
- terraforming x 2
- Monster reborn x 1
- Monster rincarnation x 1

- dark hole x 1

Trap:
- escape from different dimension x 2
- retrurn from the different dimension x 1
- dimensional prison x 2
