D reaper with a turbo idea in it. Pay 3, scry 3 get another source for mother which decreases all costs and helps the dp reduction effects of new Jeri and the option card it feels like a no brainer. Might even be worth going down to 1 x antibody for it.
Pilades head taken out completely because most decks that are immune to DP reduction also have destruction immunity as well so if you can't remove with -DP you are probably hosed anyway.
Daddy doesn't need to ever even show up, just keep up your removal spree with new Jeri and the option and grind the opponent out.
Might be worth considering if gatekeeper is worth it as well (probably still is) but there could be a faster option that rather than defend you just outright can hit harder than the opponent can deal with.
