Forum:What should I take out for draw power cards?

My current zombie deck is:

Monsters: 3x Zombie master 3x Pyramid turtle 1x Il blud 1x Patrcian of darkness 1x Malevolent mech - goku en 2x Getsu fuhma 1x Marionette mite 3x Soul absorbing bone tower 2x Paladin of the cursed dragon 1x Red eyes zombie dragon 1x Exiled force 1x Des lacooda

Spells: 3x Everliving underworld cannon 2x Terraforming 2x Zombie world 1x Giant trunade 1x Heavy storm 1x Mystical space typhoon 1x Call of the mummy 1x Magical stone excavation 2x Book of life

Traps: 1x Bottomless trap hole 2x Sakuretsu armor 1x Dark bribe 2x Tutan mask

This is a grand total of 40 cards and I'd rather keep it at 40 but the only draw power card I have is des lacooda which does not always work, other cards I have spare which I would like to add are a card destruction (sending zombies to the grave for me whilst hopefully geting my oppenents monsters in the grave allowing me to use book of life swiftly), a reckless greed and another des lacooda. Any tips for what I should do?
