I really like Judai and GX as a whole so Heroes are one of my fav decks, basically 2nd to Dragonmaids. I am saving up cash so i can blow my load to buy the Vision Hero engine IRL and build this, because i hav emost of it already. The deck sucks without either V-Heroes or Evil Heroes.
That junk aside, it's a fun combo deck that can put out huge boards of beaters that wipe out the opponent. I had a Hero build before so I redid it- a few things I changed out were things like Desires. Desires is way too bricky as it can banish important combo pieces like Mali a ton, so I cut it and found that i didn't have space for any more draw power.
Fire Flint Lady is a good tech if you can find space for it as it helps with field swarming and combos.
