I'm stuck between three....
1) Skull Servant Deck
So much support for this deck. Book of Lifes can revive Skull Servants, Pyramid Turtles and Mystic Tomatos can search them out, My Body as a Shield to protect your King of the Skull Servant, Level Limit Area-B and Gravity Bind where your 3000 attack or so King of the Skull Servant can still attack. So many possibilities!
2) Blue-Eyes White Dragon Deck
Easy to summon nowadays. Ancient Rule, Kaibaman, Kaiser Sea Horse, or the classic discard and revive. Also, with Five-Headed Dragon now, Dragon's Mirror would be a nice choice to add.
3) Mausoleum of the Emperor Deck
It lost some of its power with Giant Trunade restricted but it still has Dust Tornado. Clear your opponent's backfield, summon Hino-Kagu-Tsuchi, equip with Big Bang Shot and completely wipe out your opponent's hand. With Giant Trunade, his hand would include the magics and traps sent back.
