Forum:My LV Dragon Deck - Outdated??

I was digging through my Yugioh stuff and thank god I found my old LV dragon deck. Back then this deck beat a lot of my locals and won me a couple tournaments. But that was back then and now I'm just learning about Synchro cards and other godly new cards. Basically just wanna know if this deck is still "good" as it's known as the classic Horus Lockdown. NOTE: I checked some newer cards and added to it (Foolish Burial)..

Monsters: 27 Cards 3 Armed Dragon LV3, 3 Armed Dragon LV5, 2 Armed Dragon LV7, 3 Horus the Black Flame Dragon LV4, 3 Horus the Black Flame Dragon LV6, 3 Horus the Black Flame Dragon LV8, 3 Masked Dragon, 3 Luster Dragon, 3 Spear Dragon, 1 Twin Headed Behemoth,

Spells: 12 Cards 3 Level Up!, 3 Level Modulation, 2 Foolish Burial, 1 Monster Reborn, 1 Heavy Storm, 1 Mystical Space Typhoon, 1 Swords of Reveiling Light,

Traps: 6 Cards 3 Royal Decree, 1 Torrential Tribute, 1 Magic Cylinder, 1 Mirror Force,

Total: 45 Cards

I'm trying to keep the card count low, but I'd love some advice for this deck. Thanks.
