+ Blade Armor Ninja
+ C39 Utopia Ray

+ Grandsoil
+ Silent Psychic Wizard (2)

+ Mental Seeker(3)
+ Pot of avarice

This is a start. You need exactly five, if I'm correct. These fixes allow you to summon big monsters and overmind can manipulate the grave for the summon.

Most of those changes I understand, but why mental seeker and not psychic jumper? Why also do you suggest chimeratech?

Psychic jumper is inferior for a two star tuner. Krebons fits better, so if you need a two start, Krebons works wonders. Jumper's effect is horrid and for that much of a payment, you need either disrupt a play or summon something that makes you plus. Mental seeker let's you in to your opponent's deck and see what they're playing and potentially rid your opponent of key cards. Dump divine wrath. You've effect veiler.

Chimeratech is for machina based builds. Some may run cyber dragon. Some might not. But clearing out the board for a big monster is good. Although gimmicky, it still works.

Also consider
Hyper Psychic Blaster: 3K and trample. Nuff said
Meklord Wisel: good side option and can stick it to samurai
Maestroke: decent def plus BoM effect
Magical android: your paying lp for effects. Why not get them back?
Psi-blocker: your running nightmares. Might as well run this if you can. Stops plays cold or draws off a veiler.

My current psychic build runs most of the cards you have listed above. I have seekers so I will give them a shot. Basically the only warriors I will be running are Heroic Challenger. Perhaps I should ditch them too and just overhaul my Psychic Build? I will post my psychic build so you can see what I was playing. Thanks for the suggestions.

Given that more decks are starting to play heavy back rows, I have Destructotron which would help too.

You were good with the heroic challenger as it guarantees an easy utopia, blade armor etc. But if you wanna ditch it, that's cool. The idea was to use as few as earth attributes as necessary while using psychics as a support.

If you have a few moments, can you look at my deck, junk quasar
