winter variation, oll/pll, zz-b, eoline on left, zz-d (porkynator approach), zz-rainbow (my variant on zz-porky), eo-cross, eo-petrus, zz-tripod, zz-columns (my variant), zz-z (rotation), eo-roux, zz-lbl (co,cp,ep), rotationless f2l, non-matching blocks, xeoline, zz-a, ocell/cpll, color neutral (about z-axis), coll/epll
This was really fun to make. I was going to do 21, but I couldn't think of any more variants :fp .

I got slightly lucky on the LBL and OCELL solves, but I don't think too much of it.

i didn't even know there were that many variants.
yeah... I made some up. :p A bunch are just eo-hybrids with other viable methods, which made them easy to sub-20.

wow, this is really neat! but isnt the colour neutral solve just called colour neutral and the non matching blocks solve called pseudo?
My "color neutral" solve was only CN about the z-axis. This assures that I can identify and fix my bad edges in my standard orientation (WG) and then rotate in a z/z' to solve the line pieces about some other D-layer. Because this isn't true CN, I called it pseudo.

But as far as I know, my NM block solve was fairly accurate. I thought I was supposed to solve 1 or 2 f2l blocks with colors not matching the D-face and then fix that state during/after LL, which is what I did. If I've got that wrong though, let me know.

do a ZBLS variant.
um...I'm pretty sure that ZBLS just means EO during f2l. ZZ solves EO during eoline, so ZBLS is redundant. If I've got that wrong, then I did Winter Variation, which reduces the ZB cases from ~500 to 21 :p.

Why do you use an A5?
Personal preference :). It encourages efficiency.

did you memorize all ZBLL cases??
I can quickly recall algs for like 50 zzll cases and ~20 additional zbll cases. I just kept doing solves until I got a LL case that I knew that did NOT have edges phased and could NOT be solved with one of my COLL algs.
