11 Hand Traps line up.
Imperial Order is a good floodgate to have, and considering the only spell card in the deck is a playset of Pot of Cupidity.
Other Spell Cards to consider in the Main Deck would be Twin Twisters (which I am aware is in this decklist's Side Deck), Mask Change II, Foolish Burial.
Pot of Cupidity maximised, use to rush the floodgates and Hand Traps into the hand.
The Extra Deck consist mostly of cards needed for Ghost Reaper & Winter Cherries, in case some are wondering how (Card Name) can be summoned.
Localised Trunude is worth a mention. It returns all the Spell/Trap Cards in your Zone back to your hand, leaving you capable of Special Summoning your Burning Abyss monsters from hand.
I feel that the Extra Deck can benefit from a Number 30: Acid Golem.
