1st overview:
hmm....
I dunno...
IMHO Psychic OTK is just being an overkill or killed before the action performed.
but if you want it that way, it's your call.
anyway my fix:
-1 Overdrive Teleporter (2 Overdrive with 4 target will most likely be a dead-draw because you must summon exactly 2 monster from deck.)
-1 Snail-1 PoC-1 Krebons-1/2/3 Chain Destruction, you can side it maybe?(i dunno what it serve there actually)
+1 Psychic Jumper(you can combo this card with pandaborg/Doctor Cranium/or atleast mind master when you are in a pinch. with him and cranium in your graveyard, and you draw power well, that's a good news after all :p)
+1 Pandaborg this card may thin the deck while at the same time serve as Human Borg fodder.
+1 Power Well (well you can serve this card as draw from graveyard if you have at least 1 card summonable)
+1 Doctor Craniumalso "Return from Different Dimension" might come in handy for late game.
Extra-Deck;
-1 HPB no more chance to summon him after this fix
-1 LifeTrancer only helpful to summon HPB IMO?
-1 Ancient Fairy Dragon (don't tell me you gonna destroy your own field with her effect lol)
+1 Catastor +1 Scrap Archfiend (Highest atk point for level 7 synchcro monster)
+1 Trishula (can be easily summoned with Mind Master + any psychic monster + Power Well)
i'd rate it 7/10 because i personally prefer control over beatdown
as for side note: becareful with zombie world because it'll prevent you from doing anything because all your monster is no longer psychic but zombie.
BRL/Power Well/Psychokinesis/HumanBorg/Snail/Commander wouldn't be able to be activated
