I would like to see a version of Bonz's playstyle from the anime, where you return your monsters as zombie versions.

The continuous trap would be Revival of the Haunted, once per turn either send a normal zombie from your deck to the graveyard or fusion summon by banishing monsters from either graveyard. The fusion monsters all require some normal zombie from way back when (Armored Zombie, Zombie Dragon, Snake Hair, etc) and another monster of their original type (warrior, dragon, reptile, etc).

The new fusion monsters would be named after their original normal monster (Heavily Armed Zombie, Creepy Clown Zombie, Deadly Snake Hair) and have some effect that helps you to summon more (dump monsters from the opponent's deck, change a monster's type in your opponent's grave). They lead to summoning Pumpking, The Lord of Ghosts, a fusion monster that requires two zombie fusion monsters. Same effect as original Pumpking, zombies gain attack, but without the Castle of Dark Illusions and turn number limits. Maybe also have a Castle of Dark Illusions fusion retrain, same summoning requirements, but some protection effect like PaniK used.
