Guys, I just realized this Horus deck is 12 years old. Here's my attempt to refit this deck to make it finally reach the potential I saw in it over a decade ago.

Extra Deck:
King Dragun

Main Deck:

Monsters:
Horus LV8
Horus LV6 x2
Horus LV4
Jinzo
Prime Material Dragon
BEWD
Gorz
Lord of D x2
Divine Dragon Ragnarok x2
Mirage Dragon
Twin Headed Behemoth
Masked Dragon x3
Sangan
Des Feral Imp

Magic:
Dragon's Mirror
Polymerization
Level Up x3
Magical Mallet x2
Flute of Summoning Dragon
Stamping Destruction
SoRL
Raigeki
MST
NoC
Soul Exchange

Traps:
Mirror Force
Torrential Tribute
CotH
Royal Decree
Waboku x2
DNA Surgery

I used to have Armed Dragons in this deck. I took those out to focus on Horus and the lockdown strategy with Jinzo, Mirage, Decree, Lord of D, King Dragun, and Prime Material. DNA Surgery is in there to make the effects of Lord of D and King Dragun apply to every monster on the field. I'm looking for suggestions for Xyz and Synchro monsters to add to my Extra Deck.

OMG somebody else is here
