The Tech X thing was what I planned to do from the beginning, but caused too many issues, so I scrapped it. Your idea for Mars is too similar to Bomb Bag's synergy, so sorry but no. Lastly, the Aries thing just doesn't make much sense to me, as it would just make the dash over faster, which is an anti-synergy in most cases. Great ideas, but sorry, I won't be adding any off these.

Lodestone/Strange Attractor: Draws in enemies toward the dash (to help get anything just out of reach)?

Good one! I'll add this in the next update!

(Just spit-balling possible ideas, I don't necessarily expect these to be added )
The Parasite: 50% strength tears split off
Mom's Contact: chance to freeze
Ghost Pepper/Bird's Eye: drops a few flames
Marked: charge towards crosshair (idk if this one is even possible)
7 Seals: little harbinger charges with you
Dead Tooth: small toxic aura around Isaac
Rotten Tomato: chance to mark
Number Two: drops butt bombs
My Reflection: charge forwards, then backwards

Trisagion: Creates a giant Trisagion blast around Isaac that sticks to him for the duration of the charge, doing damage to enemies touched by it every tick. Essentially increases the charge's damage and range.

This is loosely based off of the attack "Blazing Star", Marisa Kirisame's Last Word from Touhou Eiyashou ~ Imperishable Night.

I like it! I'll write it down.

Death's Touch/Mom's Knife: Swing a scythe in front of you as you dash.

Rubber cement: when it dash and hits a wall, it bounces back and moves again
Little Horn: Can generate little horn's hands
Dead eye: Damage increases the more enemies you kill, if the dash fails the damage returns to normal
Eye of Belial: killing an enemy will cause the pony to redirect to the one behind with more damage (? dont know if it is possible

I wonder if there is a way to make a cross shot of light beams to happen at the wall collision If you had Revelation.

Can you rephrase that? I don’t know what you mean.

Dead Bird: A horde of dead birds will fly behind you across the room.

if you have god's flesh it could shrink anything you hit
