Bad deck is bad :/
1st of all, there isn't any dragon theme in the deck. I can see arm dragons but the cards in the deck doesn't really help them much.
There are many Dragon decks such as:
SOL Dragon
SOL Demise
SOL Sniper
SOL Genesis
Hopeless Dragon
Dragon Nohr
Dragon Exodia Turbo
Deep Draw Dragon
Disaster Dragon
Horus Disaster
Twilight Disaster
Spirit Well Disaster
Personally, I love the SOL variants
Arm Dragons are not popular in the Dragon Archtype as their effect easily triggers Starlight Road, Stardust dragon, My body as a Shield and etc.
Looking at this deck, it just looks like a dragon deck with SD01 and SD13 cards combined in the deck. Dragon's greatest advantage is probably bypassing the Tribute mechanic. REDMD allows a +1 every turn and it's the boss monster of Dragon. Therefore, Mausoleum of the Emperor is bad.
I can see that you are probably short of money to build a complete a dragon deck. If you wan some good dragon decklist, i can post it here.
I wanna help as much as I can to share my knowledge about the dragon archtype. Been playing dragon forever
I've just created this account. Originally, I was on Pojo forums and was a thread master of the dragon thread.
Good luck.
